Ethylene glycol is to be cooled in a 48 ft long counter flow double pipe heat exchanger consisting of 2" Type M brass tubing for the inner tube and 4" Type M tubing forming the annulus. Glycol flowing through the inner tube enters the heat exchanger at 190 F at a flow rate of 18 lbm/s. Water, acting as the coolant in the annulus, enters at 40 F at a flow rate of 25 lbm/s. Find the product UA for the heat exchanger, outlet temperatures of the glycol and water, and the pressure drop of each stream. (
