01: Find the area of rapid sand filters and find the dimensions (if fivé units are used), for the followings: • Maximum daily demand is (12 x 10 l/day). Assume rate of filtration is (4500 l/m².hr). • Water required for backwash is (3%) of maximum daily demand. • Assume (30) minutes required for stopping backwash and returningʻthe filter to service. Use L =1.3 W A = rate of filter
