Air (Cp = 1005 J/kg °C) enters a cross-flow heat exchanger at 10 C at a rate of 3 kg/s, where it is heated by a hot water stream (Cp = 4190 J/kg °C) that enters the heat exchanger at 95 °C at a rate of 1 kg/s. Determine the maximum heat transfer rate and the outlet temperatures of the cold and the hot water streams for that case.
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.
Air (Cp = 1005 J/kg °C) enters a cross-flow heat exchanger at 10 C at a rate of 3 kg/s, where it is heated by a hot water stream (Cp = 4190 J/kg °C) that enters the heat exchanger at 95 °C at a rate of 1 kg/s. Determine the maximum heat transfer rate and the outlet temperatures of the cold and the hot water streams for that case.
