1.) a) Water in a piston–cylinder assembly undergoes a constant-pressure process at 30 bar from T1 = 255.1°C to saturated vapor. Determine the work for the process, in kJ per kg of water. b) A piston-cylinder assembly contains 4.4 kg of water at 238oC and 3 bar. The water is compressed to a saturated vapor state where the pressure is 53.9 bar. During compression, there is a heat transfer of energy from the water to its surroundings having a magnitude...

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.

A piston–cylinder assembly contains ammonia, initially at a temperature of -20°C and a quality of 40%. The ammonia is slowly heated to a final state where the pressure is 6 bar and the temperature is 100°C. While the ammonia is heated, its pressure varies linearly with specific volume. For the ammonia, determine the work and heat transfer, each in kJ/kg.

Problem 6.024 SI Two kilograms of water contained in a piston-cylinder sembly, initially saturated vapor at 340 kPa, is condensed at constant pressure to saturated liquid. Consider an enlarged system consisting of the water and enough of the nearby surroundings that heat transfer occurs only at the ambient temperature of 25°C. Assume the state of the nearby surroundings does not change during the process, and ignore kinetic and potential energy effects For the enlarged system, determine the heat transfer, in...
