7-126 A well-insulated, thin-walled, double-pipe, counterflow heat exchanger is to be used to cool oil (cp = 2.20 kJ/kg · °C) from 150°C to 40°C at a rate of 2 kg/s by water (cp = 4.18 kJ/kg · °C) that enters at 22°C at a rate of 1.5 kg/s. Determine a) the rate of heat transfer and b) the rate of entropy generation in the heat exchanger. | |
