## 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

Using the information in Problem 6.1, determine the design capacities for the following:

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).

### set up and solve a case-study example of the light-intensity distribution in a photochemical reactor.

Photochemical reactor modeling: a case-study problem. Although radiation is important in heat transfer, an analogous model can be used in the design of photochemical reactors. The modeling of these reactors….

Secondary-emission measurement: a case-study problem. An indirect way of measuring of secondary emission from ponds or large bodies of water used in waste treatment is to measure the concentration and….

### set up a mass transfer model and evaluate the variation of the local mass transfer coefficient at various locations in the plate.

Chemical vapor deposition (CVD) on an inclined susceptor: a case-study problem. An important application of convective mass transfer theory is in CVD processes employed to coat surfaces with thin films….
