The heated water outflow from a nuclear power plant is cooled in a 50-m wide rectangular channel that has a discharge, Q = 225.0 m3/s. The Manning’s n is 0.015 and the bed slope is 5.0x10-4
A hydraulic jump occurs at the entrance of this channel, with a downstream depth equal to the uniform flow depth. What is the upstream depth, y1, of the hydraulic jump?
