MW Fg
Correction factor for Sg
Temperature (F):
Input the maximum temperature (design temperature)
T Ft
Correction factor for temperature
Pressure:
Input the lowest pressure possible.

If given in PSIA, subtract 14.7 and enter in PSIG cell C6
PSI PSIA
Volumetric Flow (SCFM):
If you have ACFM, use the conversion below determine the value to input for SCFM Qsg.

IMPORTANT: IF THIS INVOLVES A RECIPROCATION COMPRESSOR OR PULSATING FLOW, DOUBLE THE Qsg VALUE
Qsg    
Weight Flow, lbs/hr:
You use EITHER SCFM Qsg OR weight flow lbs/hr which is converted to SCFM Qsg and then used above for SCFM Qsg
(Converted weight flow to input as SCFM Qsg)

SCFM of equivalent air:
(corrected to 14.7 PSIA and 60F)

CALCULATED SEPARATOR SIZE REQUIRED
For all separators except Receiver Style and based upon approximate inlet ID (inches) Standard Separator Size:
If within 0.1 to the next standard size, consider going up another full size
   
For receiver style separators, due to extra complexity internally they are always a little larger for a given flow Receiver Separator Size:
Input a separator size equal to or larger than the calculated size required to achieve the required removal rate based upon the style/efficiency. It is common to oversize the body and attach smaller connections to match piping to handle higher liquid loads. CHOSEN SIZE:
Enter the separator size to determine performance data
 
Maximum Capacity (SCFM):
Accurate to within 2% for 6" to 32" sizes, within 4% for all other sizes
(Qc)
Maximum Capacity:
Equivalent maximum capacity converted from SCFM to lbs/hr.
lbs/hr
% of Maximum Capacity:  
Maximum Capacity ∆P:
Differential pressure for the maximum capacity ±0.2 Accurate, most accurate to positive pressure to 500 PSI
PSI
Actual ∆P:
Calculated differential pressure based upon customers flow rate
PSI
Used to properly size drain trap and to ensure the volume of entrained droplets anticipated can be accommodated by the chosen separator size MAXIMUM SEPARATION RATE BY SEPARATOR DESIGN
% of Weight Flow lbs/hr: GPH: GPM:
To approximate "slug" handling capability, for T, TS and R styles
