The double pipe 1 m length heat exchanger is essentially a set of concentric pipes. One fluid flows within the smaller pipe and the other in the annulus. For such an exchanger (outer diameter of the inside pipe is 2 cm; inner diameter of the outside pipe is 4 cm), water flows in the annular space at an average velocity of 0.2 m/s. The water, which cools an organic flowing in the central pipe, has a temperature change from 16 to 28 . In this case calculate the heat transfer coefficient for the water assuming that the exchanger is heavily insulated and that the wall temperature on the inside of the annulus (outside of central pipe) is 30 . And heat transfer rate=?, heat transfer flux=?
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.
