Hi All,
I am trying to find out how much CO2 (ppm) would be released into a ventilated room (m3) from a faulty pressurized gas cylinder to calculate risk associated. Would anyone be able to help me with a formula? I was trying to work with V=nRT/P but wasn't sure how do I translate the outcome to get the ppm released relative to room m3 and air ventilation that works against the CO2 exposure? Time of exposure varies in this dynamic process so time would be another variable that needs to be considered.
Co2 gas cylinder: F size (22kg) - liquid phase >99.9% (v/v)
Cylinder pressure: 5700 kPa
Outlet pressure (reduced through regulator): 150 kPa
Connection outlet: 10 mm
Room size: 60.5 m3
Air ventilation: 161 L/sec
Room temperature: 20 degrees Celsius
I guess there is a difference if CO2 is released before or after the regulator regarding the pressure difference?
Appreciate your help with this.
