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
240m3
600m 3
2400m 3
6000m3
설명
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
∴ 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
