In the work of Chemical engineering, heat exchanger is an essential part of a unit operation. Double pipe heat exchanger is an excellent example to demonstrate the principle of heat transfer using a simple-structured equipment.

In this experiment we worked on concentric tube heat exchanger. The principle of this device is to cool a hot fluid or to heat a cold fluid by using countercurrent or cocurrent flow. The external surface of the exchanger is insulated to minimize losses in the system, hot water is fed through the iner pipe, with cooling water in the outer annulus.

We worked the concentric heat exchanger with different flow rates and different temperatures to measure the THout, TCin and Tcout values.
