A vertical pipe of 1 m diameter and 20 m length has a  pressure head of 5 m of oil at the upper end. When  oil flows  through  the  pipe at  an average  velocity of 4.5 m/s, the  head loss  due to  friction is 1.6 m of oil. The density of oil is 880 kg/m3  Find the pressure at the lower end of the pipe, when the oil flow is (a) upward direction, (b) downward and also draw the neat sketch.     i) Pressure at lower end when flow of oil is upward =________________ N/m2 ii) Pressure at lower end when flow of oil is downward =________________ N/m2
