Question
Problem 1:
A new building site is very flat and, to avoid excessive excava-
tion and possibly the need to pump, the sewers are to be designed
for the minimum grades possible while still achieving a self-
cleansing velocity of 0.65 m/s at peak flow. At the beginning
of the development the flow is estimated to be 10 1/s at daily
peak and, in the future, this will rise to 40 1/s. Assume k,
0.6 mm and determine an acceptable pipe size and grade.
