Water is used to cool ethylene glycol in a 60-ft-long double pipe heat exchanger made of 4-std and 2-std (both type M) copper tubing. The water inlet temperature is 60°F and the ethylene glycol inlet temperature is 180°F. The flow rate of the ethylene glycol is 20 lbm/s, while that for the water is 30 lbm/s. Calculate the expected outlet temperature of the ethylene glycol and determine the pressure drop expected for both streams. Assume counterflow, and place the ethylene glycol in the inner tube. Compose a Summary of Performance chart.

Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
