a) A system containing 2kg of water undergoes a thermodynamic cycle. The system, which initially exists as saturated liquid water at 600 kPa, is heated at constant pressure to 250C. Following that, the system pressure is reduced to 125kPa such that the volume remains unchanged. Then, the system is subjected to an isobaric compression where it is returned to its original volume. Finally, the compression continues at constant volume until the system reaches its initial state. a. Sketch the cycle on a P-v diagram with respect to saturation lines with complete labeling of pressure and specific volume. b. Determine the work involved (in kJ/kg) for each process and the net heat transfer (in kJ) for the cycle. (10 marks) a) A system containing 2kg of water undergoes a thermodynamic cycle.
