Answer and progress.
Water flows at 4.3m/s in a rectangular channel of width 3 m and depth of flow 1m. If the channel width is decreased by 0.75m and the bottom of the channel is raised by 0.25m, Find the followings: The discharge per unit width before the constriction q m3/s/m Discharge per unit width at the constriction q" = m/s/m Water depth of flow in the constriction y2 =

1. Water flows with a velocity of 3m/s and a depth of 3m in a rectangular channel. a. What is the change in depth produced by an upward change in bottom elevation of 30 cm without energy loss? b. What is the change in depth produced by down step of 30 cm without energy loss? c. What is the width of the channel to cause a choke if the total discharge is 27 m3/s?
A 8-m wide rectangular channel carries a flow of 96 m3/s at a flow depth of...
A 8-m wide rectangular channel carries a flow of 96 m3/s at a flow depth of 4 m. The channel width is constricted to 6 m in a length of 5 m. Assuming the channel transition has straight and vertical sides, and there are no losses, plot the water-surface profile in the transition. Hint: you should find the water depth when the channel width is 8 m, 7.5 m, 7 m, 6.5 m, and 6 m.
Water flows within the 4-m-wide rectangular channel at 25 m3/s.
Water flows within the 4-m-wide rectangular channel at 25 m3/s. Take yA = 0.4 m. Part A Determine the depth of flow yB at the downstream end. Part B Determine the velocity of flow at A.
The channel transports water at 6 m3/s. The depth of flow is y = 1.5 m
The channel transports water at 6 m3/s. The depth of flow is y = 1.5 m. Suppose that d = 3.5 m. (Figure 1) Water flows in a rectangular channel with a velocity of 4 m/s and depth of 2.9 m. Part A What other possible speed of flow provides the same specific energy for the same volumetric flow? Part C Determine the specific energy of the flow. Part D Determine the minimum specific energy of the flow.
