The relation between the maximum and average rate of flow of sewage (Qmax and Qavg) for a residential area with a population ‘P’ can be expressed by Babitt’s formula which is given as:
1
\(Q_{max} = [1+{14\over {4+P^{0.5}}}] Q_{avg}\)
2
\(Q_{max} = {2\times5\over P^{0.2}} Q_{avg}\)
3
\(Q_{max} = 2[1+{14\over {4+P^{0.5}}}] Q_{avg}\)
4
\(Q_{max} = {5\over P^{0.2}} Q_{avg}\)
