If the channel flow in problem 25 is reversed so that it moves from right to left and the pitot tube reading is unchanged, what is the new velocity?

A Parshall flume is used to measure discharge in a channel. The throat width is 9.0 inches. If the measured depth, H, is 71 /2 inches, what is the discharge?

A Parshall flume with a throat width of 2.50 feet is used to measure discharge. If the measured depth, H, is 1.8 feet, what is the discharge?

A Venturi meter with a throat diameter of 4.00 inches is installed in an 8.00-inch-diameter pipe. Piezometer readings from the pipe centerline are as follows: upstream, p1/g 5 1.64 ft, and throat, p2/g 5 0.88 ft. What is the discharge in the pipe?
