R = b*d/b+2*d.
V = c*√r*s.
Q = a*v.
V = c*√r*s.
Q = a*v.

V = C(mi)^0.5.
m - hyd mean depth A/P.
i-slope.
Q = AV.
m - hyd mean depth A/P.
i-slope.
Q = AV.

Hydraulic radius = 1.5.
Hydraulic mean depth = (area/top width),
= 18/6,
= 3.
Hydraulic mean depth = (area/top width),
= 18/6,
= 3.

@Deep the way you find velocity is wrong.
The correct way to find velocity is v=c (mi) ^0.5.
And.
Rest of the all calculations are correct.

Rec-perimeter (weted) = 3+6+3 = 12m.

Thank you for explaining.

Hydraulic depth = area/top width.
H D= 6 * 3/6 = 3m.
But in answer is given hydraulic mean depth is 1.5m this one is hydraulic mean radius.
H D= 6 * 3/6 = 3m.
But in answer is given hydraulic mean depth is 1.5m this one is hydraulic mean radius.

It is an opened channel so there is no one side length.
2b+L=p.
2b+L=p.

Wetted perimeter =2*h+b,
=2*3+6
=6+6.
P=12.
=2*3+6
=6+6.
P=12.

Perimeter of rectangular notch = b+2h.
So, 6+(2*3)=12m.
So, 6+(2*3)=12m.
