One pound-mass of water at 600F expands against a piston in a cylinder until it reaches an ambient pressure of 14.7psi, at which point the water has a quality of 90%. It may be assumed that the expansion is reversible and adiabatic.
a) What was the initial pressure in the cylinder?
b) How much work is done by the water?
c) Sketch the process on a p-v diagram
d) Sketch the process on a T-s diagram
