Water flows at a depth of 0.7 m and velocity of 3 m/s in a 4-m wide rectangular channel when it encounters a sudden expansion that increased the channel width to 5 meters. What will happen to the water surface at the expansion?
a. It will go up
b. It will go down
c. It will remain at the same level
d. It will undergo a hydraulic jump
A channel carries water which is forced to pass under a structure, such asShow in Fig. 2. Neglecting energy losses, calculate the pressure in thepoint 1, knowing that the speed at point 2 is 2 m/s. Data Z1 = 0.8m; L1= 1.5 m and L2 = 1.0 m.
The flow rate passing through a rectangular channel with a base width of 4 meters and a water depth of 2.75 meters is 30 m3/s. This channel is narrowed as shown in the figure. If two (2) sections have a base width of 2m, what is the water depth in section (1) in meters (m)?
