A cycle composed of three processes, 1-2 : constant volume.2-3 expansion with PV = constant and 3-1: constant %3D pressure, occurs in a piston cylinder assembly. V1=0.025 m^3. U2-U1= 26.4 kJ. P1= 1.8 bar. U2=U3. Work of process 3-1 is equal to -12.3 kJ. Determine the relative increase in the value of Qcycle if the process 2-3 is replaced by a polytropic process with n=1.5. Select one: a. 88 % O b. 65 % O c. 79 % d. 93 % O e. 83 %
