Water is used to cool ethylene glycol in a 18.3-m-long double pipe heat exchanger made of 4-std and 2-std (both type M) copper tubing. The water inlet temperature is 15.6°C and the ethylene glycol inlet temperature is 82.2°C. The flow rate of the ethylene glycol is 9.07 kg/s, while that for the water is 13.6 kg/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.
