Fluid dynamics

  1. Dec 17, 2003 #1
    Given a container with a gas, assuming a constant internal/external pressure differential, with a hole of a particular diameter/area, what is formula to compute the rate at which the gas exits the hole.

    Assume we're talking ideal gas or air and anything else that I haven't given, but are needed.

    You might also assume you're speaking to someone with little or no fluid dynamics under his belt.

    it is inversely proportional to square root of molecular mass of the gas assuming ideal behaviour

    and directly proportional to Pressure and Area of hole

    I assume it would also include some constant. If so, what would the constant be for a typical ideal gas or air? Just getting it into the right ball park is fine - I'm not computing anything exact.
