(b) Show by Buckingham pi theorem that Nusselt number is a function of Reynold's number and Prandtl number in case of forced convection heat transfer.
Explanation
The Buckingham pi theorem allows us to identify the dimensionless groups that describe the problem. In this case, we can show that the Nusselt number is a function of Reynolds number and Prandtl number, which is consistent with the theory of forced convection heat transfer.
