Answer: W/m=20.94kJ/kg
Q/m=1705 kJ/kg
Applying the Energy Balance Referring to Fig. P3.71, water contained in a piston-cylinder assembly, initially at 1.5 bar and a quality of 20%, is heated at constant pressure until the piston hits the stops. Heating then continues until the water is saturated vapor. Show the processes of the water in series on a sketch of the 7-vdiagram. For the overall process of the water, evaluate the work and heat transfer, each in kJ/kg. Kinetic and potential...
