2. Freon-12, at a flow rate of 10560 kg/hr. needs to be heated from 240 K to 300 K. Ethylene glycol is available at 350 K at 100kg/hr. A typical shell and tube heat exchanger will be used. The plant manager recommends that the minimum temperature approach should be at least 10 K. He also recommends using 20 BWG carbon-steel tubing with a pressure drop not exceeding 10 psig (0.67 atm) for either the shell or tube side. The cold outlet temp must be kept at 300K. Determine the required heat exchanger area and heat duty. Ethylene Glycol T - 350 K P-2 atm Freon-12 10560 kg/hr T-240 K P. - 7.0 atm Freon-12 T. - 300K E-101 Ethylene Glycol T.-310 K
