Q1:

Water flows at a depth of 0.1 m with a velocity of 6 m/s in a rectangular channel. The alternate dpeth is

A 0.30 m

B 0.40 m

C 0.86 m

D 0.81 m

ANS:D - 0.81 m

@All.

According to me the solution is

q=v*y1 = 0.1*6 = .6 cubic meter per meter width.

Now use formula drive from equating specific energy at 1-1 section and 2-2 section.
q^2÷ 2g = y1^2 y2^2 ÷ (y one + y two) after solving y two= 1.93m.

Correct me if I am wrong.
