Overall Heat Transfer Coefficient in Heat Exchanger Formulas

Overall heat transfer coefficient is the overall convective heat transfer between a fluid medium (a fluid) and the surface (wall) flowed over by the fluid. And is denoted by U. Overall Heat Transfer Coefficient is usually measured using the Watt per Square Meter per Celcius for Heat Transfer Coefficient. Note that the value of Overall Heat Transfer Coefficient is always negative.
