Answer 1

Rate of flow

=3.5\times 40{ cm }^{ 3 }/s=140{ cm }^{ 3 }/s

=3.5×40cm

3

/s=140cm

3

/s

\therefore

∴

Amount flowed in one minute

=140\times 60=8400{ cm }^{ 3 }

=140×60=8400cm

.

Answer 2

Answer:

25200 litre

Step-by-step explanation:

Given :

Cross section of pipe = 3.5 cm²

Speed of water flowing = 40 cm/sec.

∴ Rate of flow = 3.5 * 40 = 140 cm³/sec.

Now,

Volume of water flowing out of in pipe in 1 minute :

= 60 * 140

= 8400 litre

Then,

Volume of water flowing in 3 minutes will be,

= 8400 * 3

= 25200 litre.

Therefore,

25200 litres of water is delivered.

Hope it helps!
