1. The table above has data from the experiment conducted on the
Vapour Compression Refrigerator. Plot the process on the P-h
diagram provided and find the C.O.P of the refrigerator using
actual properties of the refrigerant. (use the measured
temperatures and pressures to do the plotting)
2. Did the P-h diagram follow the path that was expected. If
yes, explain. If no, what would have gone wrong? How can you find
experimental enthalpy at state 4?
