How many litres of water flow out of a pipe having an area of cross section of 8cm2  in one minute, if the speed of water in the pipe is 40cm/sec
Asked by geethasree.vani5 | 15 Mar, 2015, 09:47: PM
Expert Answer

Area of cross section of pipe = 8 cm2

Speed of water flowing out of the pipe = 40 cm/sec

Volume of water that flows out in 1 sec.= 8 x 40 cm3 = 320 cm3

volume of water that flows out in 1 minute = 320 x 60

= 19200 cm3

= 19.2 litres
