An unfinned/mixed cross-flow heat exchager (single-pass) is used to cool down hot air from 75◦Cto 50◦C. In this process, the cooling fluid’s temperature increases from 20◦Cto 45◦C. What is the NTU for this heat exchanger?

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.
