Arefrigeration system uses water-cooled condenser for rejecting the waste heat. the system absorbs heat from a space at 25°f at a rate of 24,000 btu/h. water enters the condenser at 65°f at a rate of 1.45 lbm/s. the cop of the system is estimated to be 1.9. determine (a) the power input to the system, in kw,(b) the temperature of the water at the exit of the condenser, in °f and (c) the maximum possible cop of the system. the specific heat of water is 1.0 btu/lbm °f.
