PhysicsEasysingle choice

Two tubes $A$ and $B$ are in series. The radius of $A$ is $R$ and that of $B$ is $2 R$ . If water flows through $A$ with velocityvthen the velocity of water through $B$ is

Options:

Answer:

Solution:

Form principle of continuity

$A_{1} v_{1} = A_{2} v_{2}$

$π R^{2} \cdot v = π {(2 R)}^{2} \cdot v_{2}$

$v_{2} = \frac{v}{4}$
