For the sluice gate below, water is flowing under the gate in a rectangular channel (5 ft bottom width). Find the depth at the downstream of the hydraulic jump (y2), if y1=2 ft? Hint: first, use the conservation of Specific Energy to find Q based on yo and yı (assume negligible energy loss under the sluice gate) Find Froude number at point 1 (Fr:) Then, find y2 using Hydraulic Jump equations based on Fri and y1. Ya = 60 ft-

Consider the pressurized horizontal pipe network consisting of three pipes arranged in series. The characteristics of each pipe are summarized in the table. The flow of water at Node A is Q = 5 cfs and the pressure head at Node A is yA = 200 feet. The temperature of the water is 60° F. a) Determine the friction head loss hfric in feet in Pipe 1. b) Determine the friction head loss hfric in feet in Pipe 2. c) Determine the friction head loss hfric in feet in Pipe 3. d) Determine the pressure head ys in feet at Node B. e) Determine the pressure head yc in feet at Node C. f) Determine the pressure head yo in feet at Node D.
