Water flows at the rate of 65kg/min through a double pipe counter flow HX. Water is heated from 50deg C to 75deg C by an oil flowing through the tube. the specific heat of oil is 1.78kJ/kg-K. The oil enters at 115 degC and leaves at 70degC. The overall heat transfer coefficient is 400W/m2-K. Calculate the rate of heat transfer and the required number of tubes with OD=30mm and L=4m
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.
