Question

The area of cross section of a pipe is 3.5 cm squared. If water flows out of the pipe at a speed of 40 m/s, how much water will come out of the pipe in one minute?

Answer 1

Answer:

•Rate of flow =3.5×40cm³/s

=140cm³/s

_____________________________♡

•∴ Amount flowed in one minute =140×60=8400cm³

Answer 2

Answer:

840000$cm^{3}$

Step-by-step explanation:

Area of cross section of pipe = 3.5$cm^{2}$

Speed at which water flows out of pipe = 4000cm/s

Volume of water flowing out per second = 3.5 * 4000 $cm^{3}$

Therefore, volume of water flowing out in 1min = 3.5*4000*60=840000$cm^{3}$
