Homework Help: Fluid Dynamics Question(not too difficult)

  1. Mar 29, 2009 #1
    1. The problem statement, all variables and given/known data
    The spout heights for a container are 10 cm, 20cm, 30cm, and 40cm. The water level is maintained at a 45 cm height by an outside supply. Which water steam has the greatest range relative to the base of the container.
    I know that the one at 20cm is the greatest range already. I want to find out the actual range though.

    2. Relevant equations

    3. The attempt at a solution

    For 20 cm: V=radical(2gh)
    So I have the velocity but I am confused about how to find the range. Which formula do I use and what values go where?

    Do I use: Vfinal^2 - Vinitial^2=2aS, with S being distance
    Sfinal=1/2aT^2+ViT+Si with T=time and S=distance
