Traffic calculation

This is my first post; I would appreciate it if everyone could help me calculate the amount of gas required: For a pipe with a diameter of DN50 and a flow rate of 20 m/s, how long does it take to fill a large tank with nitrogen? The large barrel is 0.845 m tall and 0.56 m in diameter.
The volume of the barrel needs to be calculated first before anything else can be determined
I can calculate the volume of the tank; that’s no problem. It’s just that the formulas for determining the amount of nitrogen needed vary. How can I deal with this?
There’s volume and flow rate; what’s difficult about calculating the time?
What pressure will be achieved in the end? Once determined, it can be calculated using the Clapeyron equation (note that absolute pressure rather than gauge pressure should be used in the calculation)
What’s the pressure? Are you performing nitrogen displacement or nitrogen purging?
There is a significant difference in the time required to reach a pressure of 1 kilogram versus 10 kilograms; the higher the pressure, the slower the charging process. . . . . .
It is necessary to clarify what the pressure is when the tank is full, and what the temperature is
Where did you get the flow rate from?
What do you mean by \"full\"? Has the air been replaced? How much pressure? Or something else? I guess what you mean is after the air has been replaced, what level below should the oxygen content be, and what temperature should the dew point be?
To displace the air, but I’m currently using nitrogen to push from the top downward – how should this be understood?
