Design six show sand filters beds from the following data:
Population to be served = 50000 persons; per capita demand=150 lped;
Rate of filtration = 180 litres/hr/sq.m; Length of each bed = Twice the breath.
Assume maximum demand as 1.8 times the average daily demand. Also assume that one unit, out of six, will be kept as stand by.
