Answer correctly with reasonn
Water distribution mains are design for hourly demand.. Because water should be distributed to consumer for an few hours in a day, if we design for daily demand then it is uneconomical.
Reservior is built for the emergency storage of water if demand is less then excess of water store in that but if demand is more the required demand the surplus water supplied by reservior to meet the demand.. In case fire breaks in the city then max water is required which is supplied by reservior
So it is design for all of the above
Population = 20000
No. Of people in each property : 4
No. Of property :20000/4 = 5000
Water required for each property : 0.87L/day
Total average water demand : 0.87*5000 =4350 l/day
Water pump design for horly demand
Design discharge = 2.2*4350 = 9570l/day
Design discharge = max daily demand + fire demand
Fire demand = 76380L/min for 5 hour means
76380*5*60/(24*3600) = 265.2L/s = 0.265m^3/s
Fire demand = . 265+ 1.62 = 1.88m3/s

answer both accurately. answer only if u know The needed fire flow is 76380 L/min which has to be sustained for 5 hours. Maximum daily demand is 1.62 m3/s. What is the design discharge? Answer: The population of a town is 20000, that is to be supplied with water by a pump. The average property hold 4 people. Each property consumes, on average 0.871/day. Historical data suggests a peak day factor of 1.8 and a peak hour factor of 22....
