A stack gas from a chemical operation contains noxious vapors that must be condensed by lowering its temperature from 315°C to 35°C. The gas flow at is 0.70 m3/s. Water is available at 10°C at 1.26 kg/s. A two shell and 4 pass tube, counter flow heat exchanger will be used with a water flowing through the tubes. The gas has a specific heat of 1.10 kJ/kg-°K and a gas constant of 0.36 kJ/kg-°K. Calculate the logarithmic mean temperature difference (LMTD). Show your complete solution.
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.
