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

A two shell, eight tube pass STHE is to heat mineral oil from -5°C to 40°C using water
with an inlet temperature of 80°C. The mass flow rates of the water and the oil are
10 kg.s¹ and 35 kg.s¹ respectively. The Overall Heat Transfer Coefficient of the heat
exchanger is 285 W.m²2. If the diameter of the tubes is 30 mm, determine the total
length of tube required in the heat exchanger.
