Unformatted text preview: downstream section 2 of a circular pipe of diameter D in which there is a steady flow of an incompressible fluid of density ρ . At section 1 the velocity is constant; at section 2 the velocity distribution is a parabolic. The pressures are P 1 and P 2 respectively. Derive the total friction force of the fluid on the wall of the pipe between the sections 1 and 2 in terms of the given quantities, P 1 , P 2 , , L, D, and V 1 ....
