Question

Water flows into a tank, 150 metres long and 100 metres broad,
through a pipe whose cross-section is 2 dm by 1 5 dm at the speed
of 15 km per hour How much time will it take to fill the tank upto
3 metres in height?

Priyanka Kedia · Accepted Answer

Given, length of tank=150 metresAnd, breadth of tank=100 metresAmd,
we want water upto height 3 metres So,Capacity of
tank=150×100×3=45000 m3Now,Volume of water flow in 1
hour=Area of cross section×speed of water flow=2 dm× 1
5 dm×15 km=0 2 m×0 15 m×15000 m=450 m3Thus,Time
taken by pipe to fill the tank upto 3 metres in height=45000450=100
hoursHence, the pipe will take 100 hrs to fill the tank upto 3
metres in height
