Question

A hose of cross-sectional area 0.5m2 is used to discharge water from a water tanker at a velocity of 60ms-1 in 20s into a container. If the container is filled completely, the volume of the container is

Options

A) 240m3

B) 600m 3

C) 2400m 3

D) 6000m3


The correct answer is B.

Explanation:

Vol = cross-sectional area x length
∴ vol. of water disharged per sec
= 60ms-1 x 0.5m
= 30m3 5-1
=> Vol. of water discharged in the said 20s
= 30m3 x 20 = 600m3
∴ vol. of the container = 600m3
