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.)
Water is flowing in a horizontal, frictionless, rectangular channel. A smooth hump is built on the channel floor at a section and its height is gradually increased to reach choked condition in the channel. The depth of water at this section is y2 and that at its upstream section is y1. The correct statements for the chocked and un-chocked conditions in the channel is/are
A rectangular channel with Gradually Varied Flow (GVF) has a changing bed slope. If the change is from a steeper slope to a steep slope, the resulting GVF profile is
