A piston-cylinder device contains 2 kg of water which is initially a saturated liquid at 300 ∘ C. It undergoes three processes to form a cycle. The first process is constant volume, the second is constant pressure at 2 bar and the third is a polytropic process where Pv 1.1 = constant. If you can calculate the heat transfer and work (both in kJ ) for each process. Is the device a heat engine or a refrigerator? Answer Table Description Work transfer for first process (kJ) Heat transfer for first process (kJ) Work transfer for second process (kJ) Heat transfer for second process (kJ) Work transfer for third process (kJ) Heat transfer for third process (kJ) Heat engine (1) or refrigerator (2) Value Value Thank you
