for x =32
2. In a piston cylinder device with 5 kg of saturated vapor at 180 C decreases its internal energy by 1/5 as a result of condensation at constant pressure. Then, x kJ / kg heat is transferred to the system at constant pressure and 74 kJ / kg work is done with the propeller in the cylinder. (x is taken last two number of each student number) a) Find the degree of quality of the fluid as a result of condensation. (5 POINTS) b) Find the total energy change in the system. (7 POINTS) c) Show the changes in the system by drawing the P-v diagram. Please indicate the values. (8 POINTS)
