Min v = 0.45.
b= 2d,
q = AV.

1.5 = b*d *0.45.
1.5= 2d*d*0.45 ,,d^2=1.5/0.9= 1.36.
d=1.36.

I think the given question is wrong.

Because units of discharge is cubic meter per sec.

Kindly help me,

If ::h = 0.88 then by width= 2h, it becomes equal to = 1.76.

It means we have to design the sewer for high velocity.

According to me, it is (Q/v) = 1.5 * 0.9 = 1.35.

@Roy

Te answer is 1.76 because of 0.88x2=1.76.
