Question

a housing society has a common water tank for 500 houses Water
is pumped into the tank through a pipe which has internal diameter
7cm and flow of water in the pipe cant be 70cm/s more How many
litres of water is pumped daily in the tank if the pump can operate
for 2hours daily

Priyanka Kedia · Accepted Answer

Given, diametre of pipe=7 cmSo, radius of pipe=72cm=3 5 cmAnd, rate
of flow of water in the pipe=70cm/secThusVolume of water flowing
out per second=Volume of pipe=Area of cross-section× rate of
flow of water=πr2× rate of flow of water=227×3
52×70=2695 cm3Now,Volume of water flow in 2
hrs=2695×2×3600=19404000 cm3=194040001000lt=19404
ltSince there is common water tank for 500 housesThereforeAmount of
water, which is pumped daily in the tank=500×19404=9702000 lt
