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.

A piston/cylinder assembly with a spring contains 0.075 kg of water. The piston is initially resting on the stops and the water has a temperature of T1 = 80°C and a quality of x1 = 30%. Heat is added to the water causing the piston to lift off the stops, rise up and compress the spring. Heating contin- ues until a final state is reached and the pressure is 200 kPa. The vertical distance between the top of the piston when it is resting on the stops and the bottom of the spring is Ay = 0.6 m, as shown in the figure. Assume the piston is massless (m, = 0), the area of the piston is A, = 0.12 m², the spring constant is k, = 40 kN/m and atmospheric pressure is Po = 100 kPa. a) Determine the volume, pressure and temperature of the water when the piston just lifts off the stops, V2, P2 and T2. b) Determine the pressure and specific volume of the water when the piston just touches but is not yet compressing the spring, P3 and v3. c) Determine the final volume of water in the piston/cylinder…
