5. A conical pipe has diameters at the two ends of 1.4 and 4.2 ft and is 45 ft long.It is vertical, and the pipe friction head loss hu is

5 ft for flow of water in either direction when the velocity at the smaller section is 27 fps. If the smaller section is at the top and the pressure head there is 8.8 ft, determine the head at the lower end when the flow is (a) downward and (b) upward. (hint: Watch "Chapter8-Conical pipe.mp4")
