In a 1-shell and 2-tube heat exchanger, cold water with inlet temperature of 20 degree C is heated by hot water supplied at the inlet at 80 degree C. The cold and hot water flow rates are 5000 kg/h and 10,000 kg/h, respectively. If the shell-and-tube heat exchanger has a UAS value of 11,600 W/K, determine the cold water and hot water outlet temperatures. Assume Cpc = 4178 J/kg K and cph. = 4188 J/kg K.
