Problem #3.15
ne spring-loaded piston-cylinder device shown is filled with 0.5 kg of water vapor that
IS initially at 4 MPa and 400°C. Initially, the spring exerts no force against the piston.
ie water now undergoes a process until its volume is one-half of the original volume
and the temperature drops to 220 °C.
Sketch the process on a p-v diagram relative to the saturation lines and critical point.
0) Sketch the process on a T-v diagram relative to the saturation lines and critical point.
c.) Calculate the final pressure of the water.
d.) Calculate the final specific enthalpy of the water. [1721.5 kJ/kg)
