(THERMODYNAMICS) A vertical cylinder fitted with a frictionless piston contains 1.5 kg of H2O initially at 100 °C, 400 kPa. If the volume of the system reaches 0.5 m3, the piston hits a set of stops and is restrained from further upward travel. The system is heated to 200 C. (Use saturated water tables, steam tables, and superheated tables as necessary)

a) If the piston reaches the stops, determine the temperature and pressure when the piston first touches but exerts no force on the stops. If the piston doesn’t reach the stops, find the final volume. Clearly show how you determined whether or not the piston reaches the stops.

b) Calculate the heat and work for the entire process.

c) Show the entire process on a T-v and P-v diagram including the saturation curve.

A cylinder fitted with a piston has an initial volume of 0.1 m3 and contains nitrogen at 150 kPa, 25 0C. The piston is moved, compressing the nitrogen until the pressure is 1 MPa and the temperature is 150 0C.
