Problem 6.035 SI One kilogram of ammonia initially at 8.0 bar and 50°C undergoes a process to 3.3 bar, 20°C while being rapidly expanded in a piston-cylinder assembly. Heat transfer between the ammonia and its surroundings occurs at an average temperature of 40°C The work done by the ammonia is 40 kJ. Kinetic and potential energy effects can be ignored. Determine the heat transfer, in kJ, and the entropy production, in kJ/K. Step 1 Determine the heat transfer, in kJ....

A piston-cylinder assembly contains propane, initially at 27 °C,
1 bar, and a volume of 0.2 m3 . The propane undergoes a process to
a final pressure of 6 bar, during which the pressure-volume
relationship is pV1.1 = constant. For the propane, evaluate the
work and heat transfer, each in kJ. Kinetic and potential energy
effects can be ignored.
