Question

The relation between the maximum and average rate of flow is defined by ___________

(a) QMAX = (1 + 14/(4 + P^0.5)) * QAVG

(b) QMAX = (1 + 1/(4 + P^0.5)) * QAVG

(c) QMAX = (1 + 4 + P^0.5) * QAVG

(d) QMAX = (1 + P^0.5) * QAVG

I got this question in homework.

This interesting question is from Dry Weather Flow in chapter Water Supply for Building, Collection and Conveyance of Sewage, Waste Water Flow Rate of Environmental Engineering

Answer 1

Correct option is (a) QMAX = (1 + 14/(4 + P^0.5)) * QAVG

To explain I would say: According to Harmon’s formula, the maximum  and the average rate of flow is defined by  QMAX = (1 + 14/(4 + P^0.5)) * QAVG  where P is the population in thousands.
