### C.11Emission Rate Calculations

– Stack Diameter, D S 26 in – Stack Area, A S 3.69 sf – Stack Pressure, P S 29.78 in Hg – Stack Temperature, T S 152 F, 612 R – Sample Pressure Drop, Δp 0.3087 in Hg Further stack calculations use the pitot coefficient, C p, and the velocity equation constant, K p, which depends on the units of measure used. Measured parameters are ...
