X=Vo*tfall

Bernoulli Eq: [tex]\frac {p}{\rho}+\frac{V^2}{2}+gz=const[/tex]

I used B.E. to find an expression for the velocity of the exit jet:

[tex]V_o=\sqrt{2g(H-h)}[/tex]

For some reason I am confused as to how to find an expression for t_fall ?

I know it should be easy, but I am under the impression I am supposed to use the B.E. to find it....

Any hints?

That's not how I read the problem. You've used B.E. to find V0. The rest is just projectile motion.

Oh. Easy Enough then :smile:

Thanks again Doc!

t=sqrt(2h/g)
