Dimensional analysis in mass transfer

We consider, a case of convective mass transfer where a fluid is flowing by forced convection in a pipe and mass transfer is occurring from the wall to the fluid. The fluid flows at a velocity v inside a pipe of diameter D and we wish to relate the mass-transfer coefficient /c to the variables D, p, p, v, and D g. The total number of variables is = 6. The fundamental units or dimensions are u = 3 and are mass M, length L, and time f. The units of the variables are 

We choose the variables D g, p, and D to be the variables common to all the dimensionless groups, which are 

Solving these equation simultaneously, a = — 1, b = 0, c = 1. into Eq. (7.8-2), Substituting these values
