If you want to know the derivation of the formula, try this:
ppmvd = (lbmol NOx/10^6 lbmol FG_dry) * (1 FG_dry/(1-water fraction)* FG_wet) * MW_NOx / MW_FG * (lb FG/MM BTU_HHV)
The last factor lb FG/MM Btu depends on excess air and fuel type. You can have this info handy if you use any...
Hi all,
I'd like to calculate the average flowrate of process feed over a short period of time (say 4 mins) when one tube ruptures. The instantaneous flowrate would equal the sonic velocity multiplied by tube cross sectional area, but how long the sonic flow rate is maintained, and how the rate...
