Homework Help: Fluid Dynamics: Siphon

  1. Jan 17, 2008 #1
    Siphon with a liquid of density P and negligible viscosity. With the bottom of the tube in the contained at point A d + h1 from point B at the top of the siphon, and the bottom of the tube extracting the liquid at point C d + h1 + h2 from the top of the siphon and h2 away from point a. (All distances are vertical).
    a) With what speed does the liquid emerge from tube at C?
    b) What is the pressure at topmost point B?
    c) What is the greatest height that a siphon may lift water?

    I figure since there are no changes in area, the velocity must be constant at all point in the tube. But as the water level drops, will the pressure in the siphon change, causing the velocity to drop?

    What is the pressure difference that is making the siphon work?

    You have not said what is d. Give a better description of the whole apparatus.
