For a city, the maximum daily demand of water is 24 × 105 litres and the filtration rate is 100 litres per square metre per hour. What is the required filter area?

Detailed Solution: Question 7

B) 1000 m2

The daily demand Q is 24 × 105 litres. The rate per day is 100 litres per m2 per hour times 24 hours = 2400 litres per day per m2. Therefore, the required area A = Q / rate = (24 × 105 litres) / (2400 litres per day per m2) = 1000 m2.
