H^2=2*20.
=6.32.
SUBSTITUTE THE VALUE IN THE FORMULA.
6.32^2/2*20+6.32^4/8*(20^3).
0.998+2.492=3.4 (approx).
=6.32.

For slope less than 1 in 25 so h/l is less than or eqal to1 in 25 so h is q.
Equal to or less than (.8).
Equal to or less than (.8).

In (h^4) / (8l^3), The Value comes out 0.008 (Almost 0%) up to filling of h=2.9. At h=3m the value comes out 0.01.
so, h=3 is the right answer.
so, h=3 is the right answer.

h'2 = 20% * 2 * 20.
= 2.826.
= 2.826.

In this case, if we neglected 2nd term the correction should be less 20%. So,(h^2/2x20)<20% or 0.2. results h<2.828 m.

@All.
Answer is 1
Very simple put tan(3°)=h/20.
You will get the answer.
h=1m.

Here, root 40 = 6.32.
Then how will get h= 3.3?
Then how will get h= 3.3?
