piston cylinder with a diameter of 12.8 inches contains helium. Initially, when the helium is at 51 ∘F and 16 psia, the piston is 10.3 inches above the bottom of the cylinder. A set of stops in the piston cylinder keeps the piston from rising above 11.948 inches from the bottom of the cylinder. a) What is the temperature of the helium inside the cylinder when the piston is barely touching the stops? ∘F b) What is the pressure when the temperature is 403∘F? psia

0.75 kg of refrigerant-134a at 120 kPa and 20°C initially fills a piston-cylinder device. Heat is now transferred to the refrigerant from a source at 150°C, and the piston which is resting on a set of stops, starts moving when the pressure inside reaches 140 kPa. Heat transfer continues until the temperature reaches 90°C. Assuming the surrounding to be at 25°C and 100 kPa, determine (a) the work done, (b) the heat transfer, (c) the exergy destroyed, and (d) the...

A piston–cylinder assembly contains ammonia, initially at a temperature of -20°C and a quality of 50%. 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.
