Water in a vertical piston cylinder is heated at constant pressure of 10 bar. It is initially at 179.9 0C and has a specific volume of 0.1 m3/kg and is heated to a final specific volume of 0.248 m3/kg. Changes in kinetic and potential energies are zero. Determine:
a) the initial quality of the water
b) the final temperature of the water vapor
c) the work in kJ/kg
d) the initial and final internal energy in kJ/kg
e) the heat transfer in kJ/kg
