IIM-A Interview: When such intense discussion followed

image courtesy :google

Interviewer 1: Why are people poor?

Student: Not very sure, sir. Please! Any options?

Interviewer 2: Oh! But you should know. It’s because they don’t have money. It’s simple.

Student:… Apologies Sirs, but isn’t this the ‘meaning’ of being ‘poor’, and not the reason?

Interviewer 2: (zapped)

Interviewer 1 (in his excitement to go one-up): “… He’s poor because he’s not earning. Hence, no money.”

Student: “… apologies Sirs again. But is he poor because he is not earning out of laziness, or he is working and not being paid, or, is he ready to work and earn, but is not getting a job.”

Interviewer 1: Have you studied Economics in your B.Tech?

Student: “No, sir our canteen supervisor in the hostel is really poor, and he has a Master’s in Mathematics”

Result: Selected!

Confessions Of An IITian: What I Learned, And Didn’t, In My 4 Years Of College(rahul maganti)

Something has been bothering me for the past few days. After days of soul searching and lonely walks across the dim-lit roads of the institute across the Powai lake, it wasn’t difficult for me to understand what this abstract thing is that has been so unsettling. And, there has been a reason for the whole storm to start in my brain. In less than a week from now, I will be sitting for my placements. For many of my friends and classmates, placements are a very big thing in life where they get to take up a much hyped-high profile, good paying job, the dreams which we were shown when we slogged nights and days preparing for "IIT-JEE, frequently splashing cold water into our almost closing eyes to stay all awake in order to ace the JEE".

The slogging ensured that a majority of us entered into these prestigious institutes with an eye on the ‘package’ and the ‘job’, and not on evolving into engineers and to develop technology. The worst, many of us will now end up as Investment Bankers, Analysts and Consultants, and not as Engineers as we have been trained for the past four years.

Exactly three and a half years ago (July 2011), I got admitted into the Metallurgical Engineering and Materials Science in IIT Bombay on a rainy July day when Bombay monsoons were in full flow. Today, as I am awaiting for the results of my seventh semester, with just one remaining, I will have to confess, with contempt and despair, that academically I stand where I had been in July 2011. I have aged four long years, or to be precise,

40 months, during my stay here in IIT Bombay.

The things I learnt and experienced here are undoubtedly numerous. The place gave me what I could have not have asked for in other institutes – a liberal space for thoughts to flourish. I have grown up all along my stay here looking at the same trees, the same roads, the same departments and the same hostels and of course, the same canteens and lounges. With every passing Bombay monsoon, I evolved as a human being pioneering different ambitions and dimensions of my life with maturity – emotional, intellectual and ideological issues, nurturing hobbies and passions. I can speak on and on of what this place has given me, but will save the same for the sentimental post which I will write towards the end of my stay here. I want to concentrate more on what I haven’t learnt.

I have enjoyed everything, literally everything, in IIT Bombay except academics, which is the main reason why I am here. The three and a half years are an academic void, which I hate to say. As I am writing this, I understand that this is going to haunt me for the rest of my life. The thought that I will leave the institute in April 2015 with the same or incremental increase in academic knowledge as I entered this institute with in July 2011 is already creeping in and is getting very hard to digest. The little I learnt during the course of mugging for exams get erased as soon as the exam is done. I am pretty much sure that I would not be able to take a paper of a course in a previous semester now.

How could I have expected something different "if I had bunked classes or just attended them for the sake of the 80% attendance rule? Waking up at 8.20 AM and dragging myself to a lecture at 8.30 AM and reaching the classroom at 8.45 AM just because the professor will force the 80% attendance rule has been part and parcel of my culture and life all along the seven semesters".

And, numerous of them went by with the professor singing lullabies in the Air-Conditioned classrooms. Not to forget, the seats are not too uncomfortable for a short nap either. Why would the consequence be something different if I had spent just the night before to study even for the end semester examinations? Why would I be academically equipped to be an ‘engineer’ if I don’t even go through the textbooks suggested for the course but end up mugging the few tutorial problems and last year examination papers during the last minute?

As I end this, I am quite unsure whether this is my experience alone or the issue of a major part of the student community. I also can’t pass on a judgement on whether it is my problem or if that is the problem of the education system. But, one thing I can tell you with a certain amount of surety is that there are many students like me and the system failed all of them. Every one of them! While I don’t deny the mindset problem, I also believe that the education system can be fixed with proper dialogue and deliberations etching a progressive, inclusive and more practical form of education. While the quality of research by the professors is unquestionable, their teaching standards definitely need improvement. "The fact that some professors have been successful in waking me up for a 8.30 AM class in the Bombay monsoons or a cold January winter is testimony of some wonderful professors we have". Sadly and unfortunately, they form a very tiny part of the professor community.The last one is the long term solution. That would have saved people like me from following this race, which I became a part of, despite several and repeated attempts by my parents to convince me to take up Humanities.

All this is propelling me to now take up further studies and stay in the academic field, this time in a field where I would not be academically handicapped after one or two years. I would want to be academically proficient, at least in a single subject which I am interested in, and subjects like Political Science, International Relations and Sociology always enticed me. This has taught me a lesson for life – "to never run a rat race until someone aims the gun at point-blank". I would not like to take up a job precisely for this reason and also would not repeat the same mistake and will consciously try to gain expertise in the field which I will chose out of choice and passion, but not out of compulsion and bad-faith.

Can we get an admission to any of the NITs/IIITs if I qualify in the JEE Mains and fail to clear the JEE Advanced?

My answer to Can we get an admission to any of the NITs/IIITs if I qualify in the JEE Mains and fail to clear the J…

Answer by Arûn Râinâ:

yes, keep calm and enjoy if you have a  good IR in JEE MAINS, you will certainly get  any NIT'S, depending upon your rank.Your admission to NIT will be done by CENTRAL SEAT ALLOCATION BOARD (csab) which gives score by that 40% boards + 60% JEE MAINS kind of theory. They will give rank list based on this scores according to which you'll be asked to fill up your choices  (NIT's plus some additional pvt. Universities ) .

If you have marks above the cut off for the JEE ADVANCED , then you can give the advance for getting selected in top IIT'S, but if by chance you didn't make into IIT'S, Then by god's grace  you have already cleared JEE MAINS, and you will get any NIT'S, upon your AIR rank.

best of luck !

Which is the best place to study for iit jee?

My answer to Which is the best place to study for iit jee?

Answer by Arûn Râinâ:

I have been asked this question quite a few times because I was not a part of a coaching institution so I’m glad I get to put this answer on paper (even if virtually) thanks to your question.

It depends on what you’re measuring the worth of taking coaching on. The one line, over-simplified answer is "slightly advantageous" for the short-term goal of clearing the JEE and "it doesn't matter" for long-term achievements.

Here's what came forth as top points:

1. Inspiration: inspiration leads to motivation, and motivation leads to action. Inspire yourself regularly by following role models.

2. Avoidance of distraction: smartphones, social media, and relationships – these are the three biggest distractions at this phase. Avoid all three as much as you can.

3. Focus: learn how to stay focussed for long. There are many focussing techniques (like meditation), which help bring laser sharp focus to your brain.

4. Eliminate learning gaps: while the full concept is too much to explain here, the gist is: make sure your foundations are solid, so you are able to build up knowledge on top of it. For eg. if you are weak in algebra or trigonometry, its going to hurt you in more advanced topics that build up on that.

5. Flow state: once again, a longer concept to talk about, but in short — when you begin studying, don't break that flow until the end of that phase of study. Constant breakage is massive waste of time.

6. Scheduling: you need to create a very tight schedule that makes sure that all weaknesses are fully covered.

7. Increasing challenge: keep challenging yourself regularly with solving increasingly difficult problems. If you aim for Everest, you will definitely manage to climb the mountains of Shimla. 😉 Try to simulate test situations as frequently as you can.

8.Eat & sleep well:Having a good diet is as much essential as studying. Your brain needs regular energy from food to work efficiently. You must have at least 8 hours of proper sleep to relax your brain.It is always better to start early and revise towards the end to come through with flying colours!!

Guwahati zone has the highest percentage of students who preferred self study for IIT JEE with 61.4% opting for it while Madras with 39.4% has the lowest number of students relying on self study for JEE preparation.The major reason for this upcoming trend in IIT preparation is the commercialization of coaching institutes and providing a one size fits all solution to IIT preparation. Those who crack IIT JEE eventually, learn at a much faster pace than others and with the batch sizes increasing to accommodate more people, there is an increasing divide within these batches which harms both the slow and fast learners

What is difference between a bushing and a bearing?

My answer to What is difference between a bushing and a bearing?

Answer by Arûn Râinâ:

A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts.

BEARING ARE OF VARIOUS, TYPES LIKE:

In electric power, a bushing is an insulated device that allows an electrical conductor to pass safely through an (usually) earthed conducting barrier such as the wall of a transformer or circuit breaker.

A bushing must be designed to withstand the electrical field strength produced in the insulation, when any earthed material is present. As the strength of the electrical field increases, leakage paths may develop within the insulation. If the energy of the leakage path overcomes the dielectric strength of the insulation, it may puncture the insulation and allow the electrical energy to conduct to the nearest earthed material causing burning and arcing.

Disaster Bushing:

  • The disaster bushing will protect the seal from hitting the inside of the stuffing box if you have a bearing failure. This is a very important feature in those applications where the product will burn or explode if overheated.
  • The disaster bushing will protect personnel if there is a massive seal failure. The majority of the leakage can be directed, down the drain connection, to a collecting tank or vent.
  • To wash away solids from the outboard side of the seal that will prevent "hang up" as the seal face wears and the seal moves forward.
  • To wash away toxic or corrosive vapors that might leak across the seal faces.
  • To control the temperature in the seal area.
  • As a back up to a heating/ cooling jacketing failure.

Disaster bushings are long narrow openings that are located between the pump casing and shaft, that limit the rate of release in event of a catastrophic seal failure.

THANKS.

What are the different types of losses in pump?

My answer to What are the different types of losses in pump?

Answer by Arûn Râinâ:

A pump can be defined as “a mechanical device that adds energy to a fluid to increase its flow rate and static pressure.This process can be accomplished with positive displacement pumps or kinetic-energy pumps.

Losses in a Centrifugal Pump

•  Mechanical friction power loss due to friction between the fixed and rotating parts in the bearing and stuffing boxes.

•  Disc friction power loss due to friction between the rotating faces of the impeller (or disc) and the liquid.

•  Leakage and recirculation power loss. This is due to loss of liquid from the pump and recirculation of the liquid in the impeller. The pressure difference between impeller tip and eye can cause a recirculation of a small volume of liquid, thus reducing the flow rate at outlet of the impeller

Head losses

Head losses are potential energy that has been lost because of frictional resistance of the piping system (pipe, valves, fittings, and entrance and exit losses). Unlike velocity head, friction head cannot be ignored in system calculations. Head loss values vary as the square of the flow rate. Head losses can be a significant portion of the total head.

Control losses

Control losses occur on the discharge side of a centrifugal pump that has been equipped with a back pressure valve to control flow rate. As the liquid flows through the control valve, energy is lost. Next to static head, control losses are frequently the most important factor in calculating the pump’s total dynamic head. For pump applications, control losses are treated separately from head losses, even though they are included in the hf term.

Why is priming necessary for centrifugal pump and not in reciprocating pump?

My answer to Why is priming necessary for centrifugal pump and not in reciprocating pump?

Answer by Arûn Râinâ:

Centrifugal pumps are a sub-class of dynamic axis-symmetric work-absorbing turbo-machinery.Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from where it exits.

Common uses include water, sewage, petroleum and petrochemical pumping. The reverse function of the centrifugal pump is a water turbine converting potential energy of water pressure into mechanical rotational energy.

A centrifugal pump converts rotational energy, often from a motor, to energy in a moving fluid. A portion of the energy goes into kinetic energy of the fluid. Fluid enters axially through eye of the casing, is caught up in the impeller blades, and is whirled tangentially and radially outward until it leaves through all circumferential parts of the impeller into the diffuser part of the casing. The fluid gains both velocity and pressure while passing through the impeller.

Priming is the process in which the impeller of a centrifugal pump will get fully sub merged in liquid without any air trap inside.This is especially required when there is a first start up.But it is advisable to start the pump only after primping.

For Centrifugal Pump, priming is required only when the elevation of liquid in the suction tank/pond is less then the elevation of the pump. Centrifugal pump can not "suck" / "pull" the liquid but it push the liquid. Liquid enter in the suction of centrifugal pump by the energy it posses (atmospheric pressure in the suction tank).

A "self-priming" centrifugal pump overcomes the problem of air binding by mixing air with water to create a fluid with pumping properties much like those of regular water. The pump then gets rid of the air and moves water only, just like a standard centrifugal pump

In order for a centrifugal pump, or self priming, pump to attain its initial prime the casing must first be manually primed or filled with water. Afterwards, unless it is run dry or drained, a sufficient amount of water should remain in the pump to ensure quick priming the next time it is needed.

https://www.youtube.com/watch?v=orfL4YMb3xE

A reciprocating pump is a class of positive-displacement pumps which includes the piston pump, plunger pump and diaphragm pump. It is often used where a relatively small quantity of liquid is to be handled and where delivery pressure is quite large.

In Centrifugal pumps we require priming while in the Reciprocating pumps when the piston or diaphragm moves backward the volume of cavity increases and pressure inside it drops, this opens the inlet valve and liquid is taken in until the differential pressure between the supply side and the chamber is zero. Then the piston or diaphragm moves forward decreasing the volume of the chamber and pressure inside the chamber increase, this opens the outlet valve and the liquid from inside the chamber is pushed outside in the discharge line until the differential pressure is zero. This cycle repeats and an intermittent discharge of fluid is obtained.

Reciprocating and rotary pumps are self-priming. This is an important consideration where a prime cannot be maintained on the pump. Centrifugal pumps are not inherently self-priming, although some manufacturers do specially design self-priming units. External priming sources, such as an eductor or vacuum pump can also be employed.

THANKS.
