Solve using NTU method. Consider a liquid (Cp = 2.2 kJ /kg·K) is cooled at a rate of 12 kg/min from 150°C to 40°C in the tube side of a double-pipe counterflow heat exchanger. Water (Cp = 4.18 kJ /kg·K) enters the heat exchanger at 10°C at a rate of 9 kg/h. The outside diameter of the inner tube is 2.5 cm, and its length is 6.0 m. Calculate the overall heat transfer coefficient. (Answer: U = 2.31 kW/m2·K)
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.
