How many liters 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 cm//sec` ?

Explanation

Let, Area of the cross-section of the pipe =`A` and
speed of the water in the pipe =`v`
Water floe out (in one second)=`vxxA`=`30xx5`
=`150 cm^3`
So, water flows out in one minute =`150xx60`=`9000 cm^3`
Since,`1 litre`=`1000 cm^3`
Hence, Water flow out in one minute=`9 litre`
