Diameter - Velocity.
<25 Cm - 1m/s.
25-60 cm - 0.75m/s.
>60 cm - 0.6m/s.
We can see the maximum velocity of the sewer is 1m/s and the minimum 0.6m/s.
<25 Cm - 1m/s.
25-60 cm - 0.75m/s.
>60 cm - 0.6m/s.
We can see the maximum velocity of the sewer is 1m/s and the minimum 0.6m/s.

Dia of sewer ----- Gradient ----- Velocity.
100 ----- 1 in 60----- 0.58 m/s
150----- 1 in 100----- 0.61 m/s
225----- 1 in 120----- 0.79 m/s.
100 ----- 1 in 60----- 0.58 m/s
150----- 1 in 100----- 0.61 m/s
225----- 1 in 120----- 0.79 m/s.

The slope value corresponding to the diameter is taken from a table given in the Indian standards.
