Water contained in a piston-cylinder assembly undergoes a process from state 1 with an initial pressure of 15 bar and temperature of 240C and cooled as it is compressed to state 2 at a constant pressure of 15 bar to saturated vapor state. Determine the work done from state 1 to 2 in kJ/kg. A Work done on the system is 30.5 kJ/kg B Work done by the system is26.0 kJ/kg C Work done by the system is 31.5. kJ/kg D Work done on the system is 24.8 kJ/kg
