Im working on an exisiting Ntirogen supply system thats used to blanket boilers and pipelines etc. at a thermal power plant. Im trying to determine the capacity of the system. I have determined the size of the liquid ntrogen tank to be 8m^3 but I'm lost on how to determine the amount of gas that can be produced from the expansion of the liquid. I'd like to assume Normal conditions. 0 celcius 1atm. Any Ideas?
