FALCO 600 Flowrate and Inlet Pressure Calculator (SVE)    
rev 5-7-20
    This calculator provides an estimate of flow through a FALCO 600 at a catalyst temperature of 330°C with the heat exchanger bypass valve closed.*    
    Alternatively, if the Flow Rate is known, Inlet Pressure can be estimated.  Catalyst Residence Time and Space Velocity may also be calculated.  
Known Inlet Pressure:
Enter Inlet Pressure (in H2O
Estimated Flow Rate  = (SCFM)
Known Flow Rate:
Enter Flow Rate (SCFM)
Estimated Inlet Pressure = (in H2O)
Space Velocity (GHSV)=
Catalyst Residence Time =
    Note: On units manufactured before 2013, opening the heat exchanger bypass valve will reduce pressure drop by approximately 4-6 in H2O  

* FALCO 600 is normally operated with heat exchanger bypass closed at concentrations < 800 ppmv.     
FALCO 600 may be operated with heat exchanger bypass open at high concentrations.

Flow > 700 scfm or < 300 scfm is beyond the normal operating range.  Inlet pressure assumes a clean flame arrestor.


Catalyst volume of the FALCO 600 = 4.9 ft3
Space velocity (GHSV) = Hourly volumetric feed gas flow rate per reaction volume
