A heat exchanger is to cool ethylene glycol (Cp = 2.56 kJ/kg.°C) flowing at a rate of 3.2 kg/s from 80°C to 40°C by water (Cp = 4.18 kJ/kg-°C) that enters at 20°C and leaves at 70°C. Determine (a) the rate of heat transfer and (b) the mass flow rate of water. Changes in the kinetic and potential energies of fluid streams are negligible. The heat exchanger is well-insulated so that heat loss to the surroundings is negligible.
