Detailed Solution
Download Solution PDFConcept:
To calculate the area of a rapid sand filter, use:
\( \text{Area} = \frac{\text{Total Water Demand (litres/hour)}}{\text{Filtration Rate}} \)
- Population = 100,000
- Demand per person = 160 litres/day
- Filtration rate = 4500 litres/hour/m²
Total hourly demand = \( \frac{100000 \times 160}{24} = 666666.67 \) litres/hour
Area = \( \frac{666666.67}{4500} \approx 148.15 \, \text{m}^2 \)
