How many liters of water flow out of a pipe having an area of cross-se

1.	How many liters of water flow out of a pipe having an area of cross-section of 5 cm2 in one minute, if the speed of water in the pipe is 30 cm/sec?
Answer» Given, Area of cross section of pipe = 5 cm² Speed of water flows through pipe = 30 cm/s So, volume of water flows through pipe in 1 second = area of cross section × rate of flow = 5 × 30 = 150 cm³ Hence, volume of water flows through pipe in 1 minute(60second) = 60 x 150 = 9000 cm³ = \(\cfrac{9000}{1000}\) = 9 liter

Answer»

Given,

Area of cross section of pipe = 5 cm²

Speed of water flows through pipe = 30 cm/s

So, volume of water flows through pipe in 1 second = area of cross section × rate of flow

= 5 × 30 = 150 cm³

Hence,

volume of water flows through pipe in 1 minute(60second)

= 60 x 150 = 9000 cm³

= \(\cfrac{9000}{1000}\) = 9 liter
