Question

Water running in a cylindrical pipe of inner diameter 7cm, is collected in a container at the rate of 192.5 litre per minute. Find the rate of flow of water in the pipe in km/h

Answer 1

running volume through pipe = volume of container

πr^2h=192.5

22/7×7/2×7/2×h=192.5

77/2h=192.5

h=192.5×2/77
=2.5

✔✔πr²h=192.5

✔✔

$\frac{22}{7} \times \frac{7}{2} \times \frac{7}{2} \times h = 192.5$

✔✔

$h = 2.5$
