Question

Water is flowing at the rate of 10km/hr through a pipe of diameter 16cm into a cuboidal tank of dimensions 22m * 20m * 16m. How long it will take to fill the empty tank? [use pi = 22/7]​

Answer 1

Step-by-step explanation:

Hai friends,

Here is ur ans;

r=8cm=0.8m

rate of flowing of water, h=10 km/h

=10×(5/18) m/s.

=25/9m/s

volume of tank=22×20×16

volume of water in 1 second =r^2×h× pie

=22/7×0.8^2×25/9

some time taken to fill the tank

=(22×20×16)/(22/7×0.8^2×25/9)

=2000×7×9

=126000 seconds

Therefore, 126000 seconds to fill the empty tank
