Oil in an engine is being cooled by air in a crossflow heat exchanger, where both fluids are unmixed. Oil (cph = 2047 J/kg·K) flowing with a flow rate of 0.026 kg/s enters the tube side at 75°C, while air (cpc = 1007 J/kg·K) enters the shell side at 30°C with a flow rate of 0.21 kg/s. The overall heat transfer coefficient of the heat exchanger is 53 W/m2·K and the total surface area is 1 m2. If the correction factor is F = 0.96, determine the outlet temperatures of the oil and air.
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.
Oil in an engine is being cooled by air in a crossflow
heat exchanger, where both fluids are unmixed. Oil (cph = 2047 J/kg·K) flowing with a flow rate of 0.026 kg/s
enters the tube side at 75°C, while air (cpc = 1007 J/kg·K)
enters the shell side at 30°C with a flow rate of 0.21 kg/s.
The overall heat transfer coefficient of the heat exchanger is
53 W/m2·K and the total surface area is 1 m2. If the correction
factor is F = 0.96, determine the outlet temperatures of
the oil and air.
