Question
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 the rate of entropy generation in the heat exchanger.
