Inlet Volume Calculations - Technical Data - Dekker Vacuum

To calculate the actual pump capacity required, we first make the conversion to ACFM based on 24” Hg. P 2 = 29.92 - 24 = 5.92” HgA. 29.92 x 100 SCFM = 5.92 x V 2 ACFM. V 2 = (29.92/5.92) x 100 = 505 ACFM. Without line losses, we would require a vacuum pump sized for 505 ACFM at 24” Hg. If we look at the effect of the inlet line and filter
