Overall Heat Transfer Coefficient Equation

Heat Transfer Engineering
Thermodynamics

In the case of combined heat transfer, it is common practice to relate the total rate of heat transfer Q, the overall cross-sectional area for heat transfer (Ao), and the overall temperature ˙Q difference (DTo) using the overall heat transfer coefficient (Uo). The overall heat transfer coefficient combines the heat transfer coefficient of the two heat exchanger fluids and the thermal conductivity of the heat exchanger tubes. Uo is specific to the heat exchanger and the fluids that are used in the heat exchanger.
