Bernoulli's equation



For d=10 cm and D=16 cm, determine the minimum flow rate that can be achieved without caitation occuring in the piping system?

thank you for helping!

use bernoullis equation:

$\displaystyle p_1+\rho gh_1 + 0.5\rho v_1^2=p_2+\rho gh_2 + 0.5\rho v_2^2$

$\displaystyle h_1=v_2=0$

$\displaystyle p_1=p_2$

$\displaystyle 0.5 v_1^2= gh_2 $

and solve for v to find minimum flow at the bottom level.But because of the change in diameter we use the $\displaystyle v_1A_1=v_2A_2$ afterwards

Since no one answered I gave it a try. Let me know if this is wrong.
