5. A compressor compresses the saturated R-134a vapor at 2 bar (State 1) to 5 bar and 50 ° C (State2) at a flow rate of 0.28 kg/s. The heat

loss from this compressor to ambient air is 2 kW. Ignoring the changes in potential energy and kinetic energy, determine (12 points) (а)The volume flow rate of R-134a at the exit. (4 Points) (b)The power needed for this compressor (in kW) (8 Points)
