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.

A double-pipe heat exchanger is used to condense steam at 40°C saturation temperature. Water at an average bulk temperature of 20°C flows at 2 m/s through the inner tube (copper, 2.54 cm ID, 3.05 cm OD). Steam at its saturation temperature flows in the annulus formed between the outer surface of the inner tube and outer tube of 6 cm ID. The average heat transfer coefficient of the condensing steam is 6,000 W/m2 ? K, and the thermal resistance of...
