Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.

Question

The pressure gauge shown in the figure consists of a spring
inside a vacuum chamber. The chamber is isolated from the
environment by a piston, which is free to move up or down. Vacuum

compresses the spring. The spring has a force constant of
1250 N/m, and the piston has a diameter of 12 mm. a) At sea
level, where ambient pressure is 1 atm, the spring is
compressed by distance x, relative to its relaxed length.
Calculate xo. b) Suppose the pressure gauge is lowered into
water at a lake. At depth D1 = 4 m, the spring is compressed by distance x, relative to
its relaxed length. Calculate x1. b) At depth D2, the spring is compressed by distance
x2 = 17.325 mm relative to its relaxed length. Calculate D2.
