How many litres 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?

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) =


= 60×150 = 9000 cm3 =
