Q: What is the heat exchanger effectiveness

Concept explainers

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.

QUESTION 6 En. Karim recently bought a 2-shell passes and 12-tube passes type heat exchanger for his metal factory to reduce the hot oil (cp = 2200 J/kg.K) temperature. The hot oil enters the heat exchanger through the shell passes at 160 °C with a flow rate of 0,2 kg/s. The coolant fluid used to reduce the hot oil temperature is water (cp = 4180 J/kg.K). Water flows through the heat exchanger pipe at 18 °C and at flow rate of 0.1 kg/s. The tube inside the heat exchanger is made of 1.8 cm diameter copper tube and the length is 3 m. If the overall heat transfer coefficient is 340 W/m².K, evaluate and discuss your finding for the following parameters; i. The maximum rate of heat transfer, ii. The actual rate of heat transfer, iii. The outlet temperatures of the water, and iv. The outlet temperatures of the oil.
