Answer / bob
It truly depends on whether the pump is a suction pump or a
pressure pump. In a suction pump, you cannot pull a pressure
greater than the atmosphere, and so the size of the column
is limited. A pressure pump, i.e., one that pumps from the
bottom rather than pulls from the top, is limited only by
the force of the pump.

Answer / arun k s
This is true in the case of a suction pump. In a suction
pump, air is being sucked from the suction pipe by the
pump. Thus the pressure inside the suction pipe reaches
nearly zero but the pressure outside the pipe will be
atmospheric. Thus the higher outside pressure make the
water to rush into the pipe until the pressure developed by
the inside water colomn balances with the atmospheric
pressure.For water, the height reqd. to develop atm.
pressure is 10m (34ft.). You cant lift water beyond that
level using atmospheric pressure.

Answer / sanju
The pump becomes ineffective, when water has to be raised
through a height grater than 30 ft., because atmospheric
pressure can support a column upto 34 ft, of water at sea
level and this is only possible when the valves work most
efficiently.

A coil consisting of 200 turns of wire has its ends connected to a circuit such that the total resistance of the coil and the circuit is 2.0 ohm. There is no source of e.m.f. in the circuit. Each turn of the coil is a square of side 18 cm, and a uniform magnetic field directed perpendicular to the plane of the coil is turned on. If the field changes linearly from 0 to 0.5 T in 0.8 s, what is the magnitude of the current in the coil while the field is changing?
