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.

2. Consider steady-state heat conduction through a cylindrical wall. The fluid on the inside is at
590 K with a heat transfer coefficient of 23 W m² K'. The temperature on the outside
surface of the wall is known and maintained at 420 K. The heat flow rate through the
cylindrical wall is 200 W per 1 m length of the cylinder. If the wall has a thermal
conductivity of 0.17 W m
The ratio of the outside radius to inside radius is 2.
