4. Use dimensional analysis to develop a non-dimensional relationship between the wall

4. Use dimensional analysis to develop a non-dimensional relationship between the wall shear stress tw of a pipe flow and the other flow-related parameters: pipe diameter (D), average velocity (V), fluid density (p), fluid viscosity (u), and surface roughness &. (Hint: use V, D, and p as repeating parameters) D Tw , E
