a. Source (m3/d).

b. Low-lift pumps (m3/d).

c. Treatment plant (m3/d).

d. High-service pumps (m3/d).

e. Distribution system (m3/d).

Problem 6.1

Estimate the water demand for a city of 100,000 people. Assume the annual average consumption rate is 647 liters per capita per day (Lpcd) and use the flow ratios given in Table 6.4 for estimating the following flow rates:

a. Average daily demand (m3/d).

b. Peak daily demand (m3/d).

c. Peak hourly demand (m3/d).

d. Fire demand (m3/d).

e. Coincident demand (m3/d).
