city with a present population of 58,000 persons used a total of 9,526,500 m3 of water during the last 12 months. On the maximum day during that period 42,000,000 L were used. Estimate the average and maximum daily flows to be expected in 10 years, when the population is estimated to be 72,500

    Step 1
    Given that:
    A city with a present population of 58,000 persons used a total of 9,526,500 m³ of water during the last 12 months. On the maximum day during that period, 42,000,000 L were used.

    Required:
    Estimate the average and maximum daily flows to be expected in 10 years, when the population is estimated to be 72,500.

    Explanation:
    “Maximum daily flow” typically refers to the highest volume of fluid, often water or wastewater, that is expected to flow through a system or facility in a single day. It is a parameter commonly used in the planning, design, and management of water supply and wastewater treatment systems.

    Step 2
    (i) Present Population = 58,000 persons
    Total water consumed = 9,526,500 m³
    Average daily per capita water demand = Total water consumed / (population × 12)

    Explanation:
    The “average daily per capita water demand” refers to the average amount of water consumed per person per day within a specific population or community. It is a key metric used in water resource planning, infrastructure design, and management to assess and plan for the water needs of a given population.

    Average daily per capita water demand = 9,526,500 × 10^3 / (12 × 30 × 58,000)
    Average daily per capita water demand = 456.25 liters per capita per day.

    Step 3
    Explanation:
    Maximum daily per capita water demand refers to the highest average amount of water consumed per person in a community or population at the time duration of a single day. It represents the peak water usage per capita within a specific time period, often 24 hours.

    Maximum daily per capita water demand = 42,000,000 / 58,000 = 724.138 LPCD.

    Average daily flows when population is 72,500:
    Average daily flows when population is 72,500 = Average daily per capita water demand × Population.
    Average daily flows when population is 72,500 = 456.25 × 72,500 = 3.3078 × 10^7 liters/day.

    Step 4
    Explanation:
    Maximum daily flow when population is 72,500 = Maximum daily per capita water demand × Population.
    Maximum daily flow when population is 72,500 = 724.138 × 72,500 = 5.25 × 10^7 liters/day.

    Answer:
    The average and maximum daily flows to be expected in 10 years, when the population is estimated to be 72,500 will be 5.25 × 10^7 liters/day.
