A tube A of radius r is connected to two other tubes B and C with the help of a junction valve. The tubes B and C have radii r2 and r3 and the flow velocity in each is v and 3v respectively. If the flow velocity in tube A is n12v, write the value of n.

Question

A tube

A

of radius

r

is connected to two other tubes

B

and

C

with the help of a junction valve. The tubes

B

and

C

have radii

\frac{r}{2}

and

\frac{r}{3}

and the flow velocity in each is

v

and

3 v

respectively. If the flow velocity in tube

A

\frac{n}{12} v

, write the value of

n
