Q1:

The sequent depth ratio of a hydraulic jump in a rectangular horizontal channel is 10.30. The Froude Number at the beginning of the jump is :

A 5.64

B 7.63

C 8.05

D 13.61

ANS:B - 7.63

D^2+D-2F^2=0.

D=Sequent depth ratio=10.30,
F=Froude number.
(10.30)^2+10.30=2F^2,
[(10.30)^2+10.30]÷2 = F^2,
F = 7.628
F = 7.63.
