Do you know the flow in some other units, either volume or moles per second.

If you know volume flow rate, you could use ideal gas equation, PV = nRT, to convert to moles/sec, and then molecular weight to grams/sec.

If you don't know the flow, I don't see how to proceed. Of the gas just stays in a container (with no hole) regardless of temperature and pressure, there is no flow (basis of tires, footballs, etc.)
