The velocity of liquid v in steady flow at a location

Last updated: 6/24/2023

The velocity of liquid v in steady flow at a location through cylindrical pipe is given by Vol 1 R 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 n 2 x 10 m s and the coefficient of viscosity of the liquid is 0 75 N sm 2 find the magnitude of the viscous force per unit area in Nm 2 at r 4 cm
