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

Water is contained in a cylinder/piston arrangement fitted with upper stops which limit the volume to
0.2 m maximum. The mass of the water is 0.26 kg, and the weight of the piston and the atmospheric
pressure are balanced when the internal pressure is 200kPa. Initially, the piston pushes against the
upper stops, and the pressure is 400 kPa. The water is allowed to slowly cool down to a temperature
of 110°C. Sketch the process on both the P-v and the T-v diagrams. Label all relevant points and assign

A piston/cylinder assembly with a spring contains 0.1 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 x, = 40%. Heat is added to the water causing the piston to lift off the stops, rise up and compress the spring. Heating continues until a final state is reached and the pressure is 200 kPa. The vertical distance be- tween the top of the piston when it is resting on the stops and the bottom of the spring is Ay = 0.5 m, as shown in the figure. Assume the piston is massless (m, = 0), the area of the piston is A, = 0.15 m?, the spring constant is k; = 50 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…
