Question:

The hot and cold inlet temperatures to a concentric tube heat exchanger are Th,i=160{eq}^o {/eq}C, Tc,i=100{eq}^o {/eq}C, respectively. The outlet temperatures are Th,o= 120{eq}^o {/eq}C and Tc,o= 135{eq}^o {/eq}C.

Determine the heat exchanger effectiveness

Determine the NTU

Heat Exchanger:

A heat exchanger is used for transferring heat or thermal energy due to the temperature difference of two fluids or more than two fluids. The fluids are separated by walls, which does not allow them to mix with each other.
