Water flows down a 15-m wide rectangular spillway and has a flowdepth of 0.3m. The spillway surface is finished concrete, with aManning coefficient of 0.015. The spillway slope is 0.11.
a) Calculate the flow velocity V 1 and flowrate Q on thespillway.
b) The slope downstream of the spillway is very mild but thewidth remains the same. Verify that a hydraulic jump can occur atthe transition from spillway to the mild slope.
c) Calculate the conjugate depth of the hydraulic jump y2 .
d) Calculate the power “killed” by the hydraulic jump in hp (1hp = 746 Watts or N.m/s)
