Question

how many litres of water flows out of a pipe having an area of cross section 5 cm squared in 1 minute if the speed of water in the pipe is 30 cm per second

Answer 1

${\bold{\huge{\green{\underline{\red{Answer:}}}}}}$

$<b>Given,$

area of the cross section
of pipe = 5 cm2

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

Now,

volume of the water flowing out of the pipe in one second = area of the cross section * 30

                                                                                         = 5 * 30

                                                                                         = 150 cm3

 Volume of the water flowing out of the pipe in one minute = 60 * 150

                                                                                  = 9000 cm3

Since 1000 cm3 = 1 litre

So, 9000 cm3 = ${\boxed{\bold{\huge{\green{9 \:litres}}}}}$

Hense, Volume of the water flowing out of the pipe in one minute is 9 litres.
