Question

Determine the normal range of water elevations for an elevated water storage tower in a community with these characteristics: Minimum allowable system pressure is 320 kPa Head loss between system low pressure point and elevated tank under average daily demand conditions is 7.2 meters. Head loss between system low pressure point and elevated tank under max hourly demand condition is 10.5 meters. . .

Answer 1

1 m water height = 9.8 KPa

low-pressure service connection is at 2.5 m then water height should me more then 3 m

b) minima allowable pressure is 320 Kpa

corresponding height = 320/9.8=32.65 m

then water height should be near about 35 m

c)

head loss 7.2 m

then for low pressure head should be 10m

d)

under maximum hourly demand head loss = 10.5 m then water height should more then 15 m
