Water at 90 ◦C and a mass flow rate of 2250 kg/h is to be used to heat ethylene glycol. Ethylene glycol is available at 30 ◦C with a mass flow rate of 550 kg/h. A double pipe heat exchanger consisting of a 34.93 mm OD (32.79 mm ID) standard copper tubing inside of a 53.98 mm OD (50.42 mm ID) copper tubing is to be used. The exchanger is 10 m. It is constructed by using “hair pin” type construction with four 2.5 m sections. Determine the outlet temperature of both fluids using a counter flow arrangement. Ignore the effect of tube bends.
