Glycerin (cp = 2400 J/kg⋅°C) at 20°C and 0.5 kg/s is to be heated by ethylene glycol (cp = 2500 J/kg⋅°C) at 100°C and the same mass flow rate in a thin-walled double-pipe parallel-flow heat exchanger. The overall heat transfer coefficient is 380 W/m2⋅°C and the heat transfer surface area is 6.5 m2. Determine the rate of heat transfer. The rate of heat transfer is _____ kW.
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.
