Question

- Two horizontal pipes of radii r end 2r are connected with one another.
Water is allowed to flow through the connected pipes. If the lengths of both
the pipes are same, the velocities of water flow through the pipes are in the
ratio of​

Answer 1

Explanation:

A1.V1=A2.V2

V1/V2=A2/A1

A1=pie.r^2

A2=pie.(2r)^2

=pie.4r^2

V1/V2=pie.r^2/pie.4r^2

V1/V2=1/4

1:4
