The velocity of liquid (v) in steady flow at a location through cylindrical pipe is given by v = v0 ( 1− r2/R2 ), where r is the radial distance of that location from the axis of the pipe and R is the inner radius of pipe. If R = 10 cm. volume rate of flow through the pipe is π/2 × 10^−2 m^3/s and the coefficient of viscosity of the liquid is 0.75 N/m^2
