3.45 A piston-cylinder assembly containing water, initially a liquid at 10C, undergoes a process at a constant pressure of 138 kPa to a final state where the water is a vapor at 149C. Kinetic and potential energy effects are negligible. Determine the work and heat transfer, in kJ/kg, for each of three parts of the overall process: (a) from the initial liquid state to the saturated liquid state, (b) from saturated liquid to saturated vapor, and (c) from saturated vapor to the final vapor state, all at 138 kPa. 3.45 A piston-cylinder assembly containing water, initially a liquid at 10C, undergoes a process at a constant pressure of 138 kPa to a final state where the water is a vapor at 149C.
