Types of Flow, Reynolds Number & Continuity

Water flows through a horizontal pipe at a speed 'V'. Internal diameter of the pipe is 'd'. If the water is emerging at a speed ' $V_1$ ' then the diameter of the nozzle is

______

Show answer and solution

Answer: (a)

Continuity: $\dfrac{\pi d^2}{4}V = \dfrac{\pi D^2}{4}V_1$ , where $D$ is the nozzle diameter.
$D^2 = d^2\dfrac{V}{V_1} \Rightarrow D = d\sqrt{\dfrac{V}{V_1}}$
So the answer is (a) $d\sqrt{V/V_1}$ .
