A hose of cross-sectional area 0.5m² is used to discharge water from a water tanker at a velocity of 60ms−³ in 20s into a container. If the container is filled completely, the volume of the container is

A. 240m³
B. 600m³
C. 2400m³
D. 6000m³

Correct Answer:

Option B – 600m³

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
