0.4 kg of Refrigerant 134a initially fills a piston–cylinder device with a volume of 15 L at a pressure of 400 kPa. The cylinder is connected to a supply line through a valve. R-134a is flowing in the supply line at 900 kPa and 45°C. The valve is opened, and R-134a is allowed to enter the cylinder. The valve is closed when the volume of the cylinder is triple and the temperature in the cylinder reaches 15°C. During the process,...

Please write equations clearly and table numbers
Refrigerant R-134A is trapped inside a piston-cylinder assembly. The refrigerant undergoes a compression process from a pressure of 400 kPa containing 55% saturated liquid to a final pressure of 600 kPa. During the compression process, a total of 110 KJ/kg of heat is transferred out while the boundaries of the cylinder are maintained at 100°C, which is also the temperature of the surroundings During this process the entropy generation is o.06749 kJ/kg K....

Arigid tank of volume 0.5 m3 is connected to a piston-cylinder assembly by a valve as shown in the diagram below. Both vessels contain pure water. They are immersed in a constant- temperature bath at 200°C and 600 kPa. Consider the tank and the piston-cylinder as- sembly as the system and the constant-temperature bath as the surroundings. Initially the valve is closed, and both units are in equilibrium with the surroundings (the bath). The rigid tank contains saturated water with...
