question

Oil is flowing at 6gal/min, inside a pipe of (1/2) in. inside diameter. If the flow is laminar, determine (a)thepressure lost per foot length (b)thevelocity at the center of the pipe (c)theshear stress at the wall (d)theradial position of the point at which the flow velocity is equalto the average velocity. For oil take the density to be 60 lb/ft^3 and its viscosity to be 0.2016lbm/ft-s.
