4.
A rectangular channel 6 m wide and 3 m deep and having a bed slope as 1 in 2000 is running full. If Chezy's constant C = 54.8, pick up the correct specification of the channel from the following :
hydraulic mean depth = 1.5 m
Velocity of flow = 1.5 m/sec
Rate of flow = 27 m3/sec
All the above.
Answer: Option

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

Thank you for explaining.

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

@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.

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