Two different piston – cylinder devices each contain 1 kg of air. Initially, the temperature T = 300 K and %3D pressure P= 100 kPa of the gases are both the same in both cylinders. However, one of the cylinders is insulated and the other is not. Now, both of these gases inside the cylinders are let to expand in quasi- equilibrium processes until their pressures reach to 50 kPa. The expansion process takes place isentropically in the cylinder 1 and in the cylinder 2 the expansion process takes place reversible and isothermally. a) Plot in Excel the P-V diagrams of both processes. (Take k = cp / cv = 1.4) %3D b) Calculate the work done by the gases.

A piston-cylinder device contains 0.1 m3 of refrigerant 134a at 0.24 MPa and 40ºC. Initially the piston is fixed with a pin. Heat is transferred now to the refrigerant from a source at 100ºC until the pressure rises to 0.28 MPa. Then, heat is given to an environment with a temperature of 25ºC at a constant pressure (the pin is pulled and in this case, the mass of the piston and the masses on it and the pressure created by the atmospheric pressure are equal to the pressure inside the cylinder) the temperature is brought to a temperature of 50ºC. a) Determine the heat and work interaction for each process b) Sketch the P-v and T-s diagrams of the processes with respect to the saturation lines c) Determine the entropy change of the refrigerant 134a during these two processes d) Determine the entropy generation during these processes.

A piston-cylinder device as shown in Figure 1-7, initially contains 0.75 kg of refrigerant- 134a at 120 kPa and 20°C.
