Velocity of escaping gas while depressurizing a tank

  1. Aug 22, 2007 #1
    HI, anyone know how to calculate the velocity of a gas escaping through a valve in a rank ? The gas is pressurized at 2psig and I can get the area of the orifice if necessary.

    The velocity is roughly equal to what Bernoulli's equation would predict, converting static pressure to velocity pressure.

    p=1/2 rho * V^2
