What will be the carrying capacity of a horizontal rectangular channel 4 m wide, conveying a discharge of 1 cumec per meter width of channel?
Right Answer is:
4.000 m3/s
SOLUTION
Given:
Rectangular channel of width (B) = 4 m
Discharge (q) = 1 m3/s
For critical flow in rectangular channel:
$q = \frac{Q}{B}$
Carrying capacity of a horizontal rectangular channel
Discharge, Q = qB = 1 × 4 = 4 m3/s
