Unformatted text preview: The velocity just upstream of the jump (location 1) is 9.50 ft/s. Downstream of the jump is location 2. Find the following (5 points each): (a) y 1 (b) y 2 (c) E 1 (d) E 2 (e) M 1 (f) M 2 . Be sure to indicate the units of all answers. If you use a figure, indicate what figure is used and all values read directly from that figure. Note: Momentum in a trapezoidal channel can be calculated with: b my y gA Q M trapezoid 3 2 6 2 2 Problem 3: (3 points) The discharge in a 10. foot wide rectangular channel is 100. ft 3 /s. The slope is 0.01 ft/ft. The flow is to encounter an upward step of height 0.50 feet. What range(s) of Manning’s roughness, n , are necessary so that the step does not represent a choke?...
