The medium is steam; the pressure on one side of the pipe is known, while the other side is at atmospheric pressure. How can the flow rate of the discharged fluid be determined?

Whether it is steam discharge or blowdown from a boiler’s drum, both involve flow from the pressurized side to the atmospheric side. If the medium parameters (temperature, pressure) and pipe diameter are known, is there an algorithm to determine the flow velocity or flow rate?
The maximum flow rate can be achieved, but the exact flow rate cannot be determined.
It’s still recommended to read books; otherwise, it’s impossible to explain the lack of appropriate conditions. There are explanations for such problems in \"Principles of Chemical Engineering\". For reference.
Are there any relevant formulas available for reference?
“\"Fluid transport\" should be able to solve your problem; for reference.
Should I choose a steam trap? If it is drum drain water, this amount is very small, estimated to be in the range of a few dozen kilograms to just over 100 kilograms. It’s superheated steam, right? If it is recommended to recycle the boiler blowdown, I can help you develop a plan; we can work together on this. Professional steam, energy-saving upgrades – contact us for details.
Oh, which steam technology company do you work for?
If a relatively accurate amount of discharge is desired each time, considering the use of a flow restriction orifice plate is advisable. Design the orifice plate based on the amount to be discharged.
I have another question: my boiler’s blowdown valve leaks internally frequently. Do you have any actual cases of this issue? And what is the typical lifespan of use? This is my 20 bar superheated steam.
