An oil of viscosity 9 poise and specific gravity 0.9 is flowing through a horizontal pipe of 60 mm diameter. If the pressure drop in 100 m length of the pipe is `1800 (kN)/m^2`, determine:

• The rate of flow of oil
• The centre line velocity
•  The total frictional drag over 100 m length
• The power required to maintain the flow
• The velocity gradient at the pipe wall
• The velocity and shear stress at the pipe wall
• The velocity and shear stress at 8mm from the wall.
