How many litres of water flow out of a pipe having an area of cross-section of `5\ c m^2` in one minute, if the speed of water in the pipe is `30\ c m//s e c` ?

Explanation

Area of the cross-section of the pipe = `5cm^2`

Speed of water flow =` 30 cm/sec`

Now, Flow of water in 1 minute =`30x60`=`1800cm`

Area of mouth of pipe =`5cm^2`

`therefore` volume of pipe = `1800xx5` = `9000cm^3`

Volume of water in litres = `9L`
