Force of Flowing Gaseous Oxygen

  1. Nov 7, 2014 #1
    Hi guys, I am trying to calculate the force that gaseous oxygen would exert if it were to flow from a tube and come to a restriction in that tube.

    I'm not sure if I am correct in my thinking, but so far, I think that the flow can be calculated by the size and length of the restriction, and then the pressure based on that flow

    Flow= (delta pressure * pi * r^4) / 8 * l * n

    And from that flow you should be able to calculate the force

    Force= density * flow volume * delta velocity

    Now, I'm thinking that this would work, but I'm not certain.
    Any help would be appreciated!

    I'm also just confused as to which units I should be using for pressure, n, and what units flow will end up as?
