A Rectangular Channel will give the Maximum Discharge if

Answer: B. Breadth is twice the depth

A rectangular channel will give maximum discharge if its breadth is twice the depth .

Solution

A rectangular channel will give the maximum discharge if (Most economical section):

1. y = B/2
2. A = 2y²
3. P = 4y
4. R = y/2
5. T = 2y
6. D = y

Where,

y  = Depth

B = Breadth

A = Area

P = Perimeter

T = Top width

D = Hydraulic depth 

Hence, a rectangular channel will give the maximum discharge if breadth is twice the depth.
