1. Water is flowing through a large circular conduit with a velocity profile given by the equation v = 9(1- r2/16) fps. What is the average water velocity in the 1.5-ft pipe?
2. Water enters a 4-in. square channel as shown at a velocity of 10 fps. The channel converges to a 2-in. square configuration as shown at the discharge end. The outlet section is cut at 30° to the vertical as shown, but the mean velocity of the discharging water remains horizontal. Find the exiting water's average velocity and total rate of flow.
