Question 3 a) From Experimental investigations it is known that the pressure drop per unit length (Ap/L) of a pipe is proportional to its diameter (d), average roughness height (Ks), flow velocity (V) and fluid properties density and viscosity. Using dimensional analysis, establish a relationship between and pressure drop per unit length and independent variables.
