Hydraulic problem , Water Main

  1. May 13, 2010 #1
    This is not a homework problem, just a discussion problem between engineers,. I would like to see what anwers others get.

    Given: A 24 inch diameter water main is operating at 40 lbs/sq. in.. A small hole is drilled in the top of the water main (not buried).

    Find: To what height will the water shoot?

    That's all the given info you get, make reasonable assumptions as needed.

    Doesn't matter if it's homework or now, you need to show your own work first. What equations and factors did you use? What answer did you get?

    Hint: it's a surprisingly easy question.

    On the surface it seems like a very easy question, it might not be a three term equation.

    Is it a hydraulic problem or a ballistic problem. I think both are involved.
