Problem 8.9: Cold water (cp=4.18 kJ/kg⋅∘C) leading to a shower enters a wellinsulated, thin-walled, double-pipe, counter-flow heat exchanger at 15∘C at a rate of 0.25 kg/s and is heated to 45∘C by hot water (cp=4.19 kJ/kg⋅∘C) that enters at 100∘C at a rate of 3 kg/s. Determine (a) the rate of heat transfer and (b) the rate of exergy destruction in the heat exchanger. Take T0=25∘C.
