Thread: HYDRULIC'S question.

A long, wide open channel has a manning number of 0.022 and a longitudinal bed slope of 1:900. The discharge is 1.25m3/s/m. Supercritical flow issues from beneath a sluice gate at the upper end of the channel. If the Channel is rectangular, determine

1. 1. Whether a hydraulic jump will occur in the channel
      
   2. The conjugate depths of any hydraulic jump formed
      
   3. The energy head dissipated by the jump
      
   4. The power per metre width dissipated by the jump.
