|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.

|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.

|@Lakshmi then 1000^2= πD^2/4.

|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.

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

It is the relation between circular and square sewer.

|The ratio of the dia of a circular section and the side of a square section hydraulically equivalent is 1.095.|
