Technical Round
*Design of Pump and
Motor for Agricultural Well
Approach:
General things I considered were Area of Land, Amount of water(depends on type
of crop), Duty cycle of motor per day etc.
From these data I got some specifications for pump like
·
Flow Rate(Q)
·
Cross section area of
Pipe etc.
·
water head(h)
·
Density of water(rho)
·
Max. Distance up to where water is to be
provided etc.
Considering these parameters, interviewer told
me to derive an expression for rating of Induction Motor. Then I simply
combined all units, broke them in SI units, compared with SI unit of Watts(P)
and got the answer as P=Q*(rho)*g*h.
So basically in this question it was not about the right answer, they
were trying to test your approach if you are told to design something.
Other questions asked were on:
* IDMT curves
* what happens when S.C. current in panel flows for time greater than rated
S.C. withstand capacity of Breaker
* 3-4 questions framed on 3 feeders having CB with different tripping time
* How a bus bar loses its mechanical strength
HR round
No questions asked
Any advice
The panelists wanted the
interviewees to relate Electrical Engg. with Mechanical.
Don't give up even
if you don't know the Answer!!!
