A hydraulic jump occurs in an open channel when the slope of the channel changes from__________ .
G1 and G2 are the slopes of the approach and departure grades of a vertical curve, respectively.
Given |G1| < |G2| and |G1| ≠|G2| ≠0
Statement 1 : +G1 followed by +G2 results in a sag vertical curve.
Statement 2 : −G1 followed by −G2 results in a sag vertical curve.
Statement 3 : +G1 followed by −G2 results in a crest vertical curve.
Which option amongst the following is true?
A hydraulic jump takes place in a 6 in wide rectangular channel at a point where the upstream depth is 0.5 m (just before the jump). If the discharge in the channel is 30 m3/s and the energy loss in the jump is 1.6 m, then the Froude number computed at the end of the jump is _________. (round off to two decimal places)
(Consider the acceleration due to gravity as 10 m/s2.)
