Question

If water flow through cylindrical pipe of dia 5 mm with speed of 10 metre per minute

Answer 1

$\huge\bf\red{Shalom!}$ FOLLOW ME❤ & Mark Brainlist _____________Answer_____

Volume flown = 1/3 PI (20)^2 * 24 = 3200 Pi

Volume flown in 1 min = (Pi* 2.5/10 * 2.5/10 * 1000) = 62.5 Pi

Therefore Time taken = 3200 Pi / 62.5 Pi = 51 min. 12 sec.

1.9625 × ${10}^{-4}$ ${m}^{3}$

step-by-step explanation:

For the cylindrical pipe,

Given,

diameter = 5 mm

=> radius (r)= 5/2 mm = 2.5 × ${10}^{-3}$ m

Now,

In 1 minute,

distance travelled by water (h) = 10 m

So, the volume of water flown in 1 min

= π ${r}^{2}$h

= 22/7 × ${(2.5×10^-3)}^{2}$× 10 ${m}^{3}$

= 22/7 × 6.25 × ${10}^{-6}$ ×10 ${m}^{3}$

= 19.625 × ${10}^{-5}$ ${m}^{3}$

= 1.9625 × ${10}^{-4}$ ${m}^{3}$
