Question
How many liters of water will flow out of a pipe having a cross sectional area 6 cm2 in one hour, if the speed of water in the pipe is 30 cm/sec?
Solution
Volume of water flown
= Area x Time x Rate
= 6 x 3600s x 30cm3/s
= 648000cm3
= 648liters ...(∵ 1liter = 100cm3)
∴ The volume of water flown is 648liters.
