depth of flow in pipes
(OP)
hi can anyone help me I have to design a foul drainage network for a housing estate. Dont have a software program so its the old fashioned way! Have most details worked out but the proportional depth of flow is what I have difficulty with. If anyone has an example of a pipe design I would be grateful!!Thanks

You can back calculate the needed sewer size using EPA's rule of 400 gpd / home X peak factor (see 10 states standard). Then use Mannings Equation solve for A using V = 2fps. You probably dont want the sewer to run more than 1/2 full worst case scenario.
10 States Peak Factor
Peak Factor = (18 + SQRT (P))/(4 + SQRT (P))
P = Population in Thousands
