Hot water (cph = 4188 J/kg*K) with mass flow rate of 2.5 kg/s at 100 deg C enters a thin- walled concentric tube counterflow heat exchanger with a surface area of 23 m^2 and an overall heat transfer coefficient of 1000 W/m2*K. Cold water (cpc = 4178 J/kg*K) with mass flow rate of 5 kg/s enters the heat exchanger at 20 deg C, determine (a) the heat transfer rate for the heat exchanger and (b) the outlet temperatures of the cold and hot fluids.
