Bernoulli Equation

  1. May 23, 2009 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    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)
