Question

Water is flowing at a rate of 5km per hour through a pipe of 14 cm diameter in to a rectangular tank of dimension 50m multiply 44m . Find the time in which the level of water in the tank will rise by 7cm

Answer 1

Answer

Water is flowing at the rate of= 5km/hr

1hr=5km

X hr=5x km=5000x

Height= 0.07m

Volume of rectangular tank=volume of pipe

L×b×h=πr×r×h

50×44×0.07=π×7×7×5000X

154=770000x

X=2 hr.
