Problem 4 (4 points): When a fluid, of dynamic viscosity u(kg m-'s!) and density p(kg m-?), flows in a circular pipe of diameter D (m), and having an average roughness of its inside wall ε (m), at a velocity V (m/s), shear stress t (kg m-'s-2) will be developed. In hydraulics, the friction factor, f, is introduced using the expression: fpV² T = 8 Using dimensional analysis, find the general relationship defining f.
