Water enters a 4-in. square channel as shown at a velocity of 10 fps. The channel converges

Question:

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.
