In a hydraulic jump occurring in a horizontal channel, the Froude's number before the jump is 10.0 and energy loss is 3.2 m. Estimate sequent depths, discharge intensity and Froude's number after the jump.

A valve is closed in 4.5 seconds at the downstream end of a 3000 m pipeline carrying water at 2.5 m/s. The peak pressure developed by the closure is: (Use g = 10 m/s², C = 10 m/s², C = velocity of pressure wave = 1000 m/s) A) 1875 kPa B 2000 kPa C c) 2500 kPa D 1667 kPa

Some students were performing a hydraulic jump experiment using a wide channel during their laboratory session. During a hydraulic jump experiment, the flow depth amplified from 0.6 m to 3 m. Estimate; a) the velocities and Froude numbers before and after the jump  b) the energy dissipation ratio

The Froude number of a subcritical stream at the end of a hydraulic jump in a horizontal rectangular channel is 0.22 The sequent-depth ratio of this jump is. （a）11.25 (b）15.25 (c）8.35 (d) 6.50
