A shell and tube heat exchanger is designed as a counter to cool a mass flow rate of 60 kg/h of engine oil (cp = 1060 J/kg oC) from 300oC to 150oC. The cooling water, cp = 4182 J/kgoC, enters the tube side (Length is 1.75 m and Outer diameter is 2.54 cm) at a temperature of 20oC. If the overall heat transfer coefficient, U, is 10.83 W/m2o C and the Capacity Ratio of the Heat Exchanger is 2.4, calculate the following: a)The heat transfer rate, b)The mass flow rate of the cooling water in the units of (kg/h), C)The surface area of the heat exchanger,
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.
