Dear All
Do you have any idea, document, article, code, guideline and etc for F&G mapping using Dispersion modeling!?
I think the idea that gas detector shall be installed on 0.5m height if the gas density is heavier than air is ridiculous! Because when gas exits from a the hole, it has its momentum and it does not have enough time to settle! this gas may settle after 20-50m from leak location.
thanks
