How To Convert F to Q?

  1. Dec 2, 2009 #1
    Hello everyone,

    I am newbie here.

    Can someone please tell me how can I convert force F into flow rate Q?

    Thanks in advance

    You can't do a direct conversion like that. They are two completely different units of measure. What are you trying to accomplish? If we know what your question really is we can probably help you.

    If you are talking about Fluids then force is generally found by

    F = rho. Q. v

    where rho is the density and v is the velocity of the fluids

    The force F and density rho are known, how do I find the velocity v? Q is the quantity I would like to know.

    If you know the crossed sectional area, A, then the volume flow rate at the crossed section can be defined as:

    Q = vA

    where v is the velocity,

    if you equate these two equations, you will get

    F = rho.A.v^2

    from this you could probably find v and ultimately, Q.
