A single-pass, cross-flow heat exchanger uses hot exhaust gases (mixed) to heat water (unmixed) from 30°C to 80°C at a rate of 5.25 kg/s. The exhaust gases enter and exit the exchanger at 225°C and 100°C, respectively. If the overall heat transfer coefficient is 234W/m K, use the NTU method to estimate the required surface area (m ).

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.
