Cold water (cp = 4.18 kj/kg⋅°c) leading to a shower enters a well-insulated, thin-walled, double-pipe, counterflow heat exchanger at 10°c at a rate of 0.95 kg/s and is heated to 70°c by hot water (cp = 4.19 kj/kg⋅°c) that enters at 85°c at a rate of 1.6 kg/s. determine (a) the rate of heat transfer and (b) the rate of entropy generation in the heat exchanger.
