Arefrigerator is used to cool water (cp = 4.18 kj/(kg. oc) & density  = 1 kg/l) from 23 oc to 5 oc in a continuous manner. the heat rejected in the condenser is 570 kj/min and the power of the compressor is 2.65 kw. determine: a) the rate at which water is cooled in l/min b) the refrigerator cop

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
