Answer:
[tex](\frac{r_1}{r_2})^2=\frac{1}{9}[/tex]
Explanation:
From the question we are told that:
Diameter 1 [tex]d_1=1.0[/tex]
Diameter 2 [tex]d_2=3.0[/tex]
Generally the equation for Radius is mathematically given by
At Diameter 1
[tex]r_{1}=\frac{1}{2} inch[/tex]
At Diameter 2
[tex]r_{2}=\frac{3}{2} inch[/tex]
Generally the equation for continuity is mathematically given by
[tex]A_1V_1=A_2V_2[/tex]
Therefore
[tex](\frac{r_1}{r_2})^2=(\frac{1/2}{3/2})^2[/tex]
[tex](\frac{r_1}{r_2})^2=\frac{1}{9}[/tex]
