Continuity Equation

  1. Aug 18, 2008 #1
    For the continuity equation (Q= Av, A is cross sectional area, v is velocity), is it independent of the radius of the pipe? If so, why?

    Well, is A independent of the pipe radius?

    The cross-sectional area is dependent on the radius.

    The velocity must increase as the radius decreases to allow the same volume of fluid to pass through over a given time.
