In rapid sand filters, the flow rate capacity is 0.3 m3/s and the filtration rate is 100 L/m2.min. When one filter is stopped the filtration rate become 150 L/m2.min. If each filter is backwashed for 5 mins and backwash rate is 60 m3/m2.hr. Find the number of filters, area of each filter, percentage of backwash water to filtered water if the filter is stopped 30 min/day. Also, find the diameter of the pipe which transport the backwash water if the designed velocity is 3m/s.
