How much steam passes through a 10-mm hole

The maximum value is 340 m/s multiplied by the cross-sectional area
If there is enough time, the steam from a boiling Pacific Ocean would also be sufficient to pass through this hole.
Assume that the \"10-mm hole\" is a flow-limiting orifice plate with a pore diameter of 10 mm; the pressure before the plate is 0.6 Mpa, and the pressure after the plate is 0.1 Mpa. If the inner diameter of the pipe is known, the mass flow rate passing through this orifice can be calculated using the formulas specified in HG-T 20570.15-95 \"Installation of Flow-Limiting Orifices in Pipelines\".
Of course, it can also be calculated using the “small-hole leakage model”.
There’s no other meaning to it; it’s just a reminder that questions should be specific, objective, and accurate.
Calculate the “local speed of sound”. Your initial and final conditions are not clear, so it’s impossible to calculate.
Thanks to everyone above; the answers are all great!
