7.8. DIMENSIONAL ANALYSIS IN MASS TRANSFER

7.8A. Introduction

The use of dimensional analysis enables us to predict the various dimensional groups which are very helpful in correlating experimental mass-transfer data. As we saw for fluid flow and heat transfer, the Reynolds number, Prandtl number, Grashof number, and Nusselt number are often used in correlating experimental data. The Buckingham theorem discussed in Sections 3.11 and 4.14 states that the functional relationship among q quantities or variables whose units may be given in terms of u fundamental units or dimensions may be written as (q − u) dimensionless groups.

We consider a case of convective mass transfer where a fluid is ...
