Water flow question

  1. May 27, 2012 #1
    Hi all!

    If I had a tube with diameter x cm, filled with water, how would I calculate the time it takes for a volume V of the water to pass a point in the tube, flowing completely due to gravity.

    Assuming laminar flow and neglecting viscosity? You also need the height of the inflow end above the outflow end - then it's conservation of energy.
