Relation between square and circular sewer :-
π * D^(8/3) = 4 * b^(8/3)
D^(8/3) = 4 * b^(8/3)
D^(8/3) = 4 * 1000^(8/3)/ 3.14
D^(8/3) = 127323954.47
Or D = 127323954.47^(3/8)
So D = 1094.82 say 1095.

d=1.094b.
b=side of square.
d=dia of crcular section.
D=1.094 * 1000 = 1094.
b=side of square.
d=dia of crcular section.
D=1.094 * 1000 = 1094.

D =1.09B,
For egg shaped sewer, D'= 0.84 D.
For egg shaped sewer, D'= 0.84 D.

de = 1.30 x((a x b)^0.625/(a + b)^0.25).
where a and b are sides of rectangle. Here a = b since we are dealing with square.

Level of sewage flow required. If 3/4 full flowing. Then calc Hyd radius of channel and equate HYD with circular section HYD.

By using manning's formula:
Discharge of square pipe = Discharge of circular pipe.
Discharge of square pipe = Discharge of circular pipe.

Two section of different shapes is said to be hydraulically equivalent if they carry same discharge while running full on the same grade and are of the same material.

Relation between circular and square sewers is (pi*D^(8/3))=(4*B^(8/3)),
where D- diameter of circular sewer and B- side of a square sewer.
where D- diameter of circular sewer and B- side of a square sewer.
