From a tap of inner radius 0.75cm, water flows at the rate of 7m per second. Find the volume in liters of water delivered by the pipe in one hour.

Explanation

Radius of the pipe =`0. 75cm`
Therefore,Area of the cross section of the pipe=`pixx(0.75cm)^2`=`1.77 cm^2`
Now,Water flows at the rate of `7m//s`=`700 cm//s`.
Therefore, volume of the water delivered per second is=`700xx1.77`=`1239 cm^3//s`
Therefore volume of the water delivered per hour =`1239xx3600`=`4460400 cm^3`
=`44604000//1000 xxL`(`1L`=`1000 cm^3`)
=`4460.4 L`
