- If I know the starting pressure and ending pressure, volume of the vessel, and time to fill. Can I determine the fill rate or flow rate?

I am looking for an equation that I can use to compute L/min or mL/min for a 480cc vessel going from 150bar to 250bar with a fill time of 6min. Sensors for flow rate at these pressures are hard to find, but I thought there might be a way to work this out with the parameters known. An equation would be AWESOME if expressed in a way that I could automate via excel or sheets. Can it be done? Is anyone willing to look at this with me? I've tried searching this a bunch of different ways, I'll say it's challenging to find... It's also outside my wheelhouse. Thank you for time in advance.
