23 - Convection - Analogies between Heat and Momentum Transfer

The advantage of the analogy lies in that the \(h\) may not be available for certain geometries/situations however, for which \(f\) value may be available as it is easier to perform momentum transport experiments and then to calculate the \(f\). Thus by using the analogies the \(h\) may be found out without involving into the exhaustive and difficult heat transfer experiments.
