GA

The OP should be very careful. Boron Trifluoride is a poisonous gas that can be very nasty.

Blast furnace and boiler flue gas with their varying concentrations of carbon monoxide gas can be just as deadly.

Eschew obfuscation.

Multiply the volume flow rate by the density of the gas at the relevant temperature and pressure conditions.

what is an Nm3/hr? I do not remember that unit of measure from screwall.

"N" stands for normal, as in normal pressure and temperature. 1 atmosphere and 25 degrees C. Normal temperature can vary between industries.

i got an answer that by multiplying density of gas to its discharge(in Nm3/hr) we could get discharge in (kg/hr). my next doubt is how to convert (Nm3/hr to m3/hr)

wouldn't you want to convert the raw number m3/hr, and convert that to Nm3/hr conditions of 1 atmosphere pressure and 298.15 K? Use the ideal gas law probably, or use a more suitable equation of state for the gas in question if the pressure and temperature are far from normalized conditions.

...or use a set of tables for the particular fluid at those different conditions of temperature and pressure. GA.
