    How to calculate fountain GPM for a fountain height of 120 feet

    Nevermind, I figured it out. So I got 861 GPM. Now I need to figure out the liquid horsepower. I have the equation LHP = (Q x HP) / 3960. Not sure what to use for HP.

    How to calculate fountain GPM for a fountain height of 120 feet

    I see. So I got 88 ft/s for my velocity. Now Q = (88 ft/s)([PI x {2in/12}^2] / 4) = 1.9198 x 60 sec = 115.1917 ft/min? How do I get to GPM?

    How to calculate fountain GPM for a fountain height of 120 feet

    Not sure how to get that. I know Q = VA, so if i knew the velocity I could get Q but not sure how.
