@Lakshmi then 1000^2= πD^2/4.
Then D=1128.

D=1.1B.

It is the relation between circular and square sewer.

@Dhanu.

How 1.094?

@Gugu.

Use Mannings formula for velocity and multiply with Area to find discharge. Hydraulic equivalent means having the same discharge. So equate discharge from both square and a circular section. You will get your answer.
