sir hydraulic radius or hydraulic mean depth depth same hain different( answer with reference )

[@faisalessakhil9222]

Q=48m^3/sec
V=1m/sec
Side slope =1:1
n=0.02
B/D=2
S=?
P=?
It is a trapezoidal canals

[@abhijeet246]

Hi Faisal, the solution to your question I an writing here
1. Both Q and V are given, so we can find flow area A simply using Q = V x A
So A = Q/V = 48 / 1 = 48 m2.
2. As it is a Trapezoidal section, flow area A = By + my^2. Now we are given that B/y = 2. So B = 2y.
Therefore A = (2y) y + 1 x y^ 2 and A is 48 m2. Solving for y we get y = 4 m. And B = 2y = 8 m.
3. As B and y are known, we can find P directly by formula P = B + 2y√(1+m2) = 19.31 m.
Therefore R = A/P = 48/19.31 = 2.48 m
4. To find bed slope S, use Manning as Manning's constant n is given n = 0.02
V = (1/n) x R^ (2/3) x S^ (1/2)
1 = (1/0.02) x 2.48 ^ (2/3) x S^(1/2)
Therefore S= 0.001191

[@nusabis7448]

is m symbol in angle?

[@abhijeet246]

m is symbol for side slope of the section. It is 1 unit vartical : m unit horizontal. For example if the side slope is 45 degrees, then slope is 1:1 so m would be 1.

[@nareshryamati7201]

About hydraulic radius and hydraulic mean depth you are telling just formula but not explaining what it mean really in practical by using that diagram. It will be better to get that original visualisation of hydraulic depth rather than a bihearted firmulae

[@abhijeet246]

Good suggestion.. You can also share what you know.. It will be helpful to everyone..
