    We have a cone, standing horizontally. A fluid enters to cone from the larger cross-section and makes centrifugal movement. Fluid moves towards small cross-section. At the small cross-section part we have to separate some particles from the fluid by centrifugal force.
    I would like to know that will the separation be more efficient if we have a smaller or larger cross-section at the end? or for example, is a cylinder more efficient or not?
    And how can we prove that?

    Thanks

    The equation for radial acceleration is given by the equation - Radial Acceleration = v^2 /r

    v = rotational speed x r

    so the radial acceleration as a function of rotational speed

    Radial acceleration = rotational speed ^ 2 x radius

    As a result the fluid is going to move from the small end of the cone to the large end and not the way you have indicated unless you have a very big driving force.
