At a point A in a horizontal 12" pipe (/ = 0.020) the pressure head is 200 ft. At a distance of 200 ft from A the 12" pipe reduces suddenly to a 6" pipe. At a distance of 100 ft from this sudden reduction the 6" pipe (/ = 0.015) suddenly enlarges to a 12" pipe, and point F is 100 ft beyond this change in size. For a velocity of 8.025 ft/sec in the 12" pipes, draw the energy and hydraulic grade lines. Refer to Fig. 8-3.
