    Convert ppm NOx to lb/MMBtu NOx

    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...

    hydrocarbon flow rate at tube rupture

    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...
