A one-shell-pass, two-tube-pass heat exchanger is to be used to cool ethylene glycol with water. The ethylene glycol (c_p = 2.505 kJ/kg · °C) enters at 85° C flowing at 1 kg/s; the water (c_p= 4.18kJ/kg · °C) enters at 15° C, flowing at 2 kg/s. If the cooling water exits the heat exchanger at 31° C, find the outlet temperatures of the ethylene glycol and the rate of heat transfer between the two flows.
