Using a well-insulated heat exchanger, groundwater with a temperature of 100 ° C and a flow rate of 1 kg / s (cp -4.20 kJ / kg ° C), a temperature of 30 ° C and a flow of 0.7 kg / s (cp = 4.19 kJ / kg ° C) will be heated to 70 ° C. Calculate (a) the amount of heat transfer and (b) the amount of entropy generation that occurs in the heat exchanger.
