WebDec 9, 2008 · The drag coefficient on each particle, which is calculated using standard correlations (Schiller Neauman), must be divided by the Cunningham correction factor. … WebThe slip correction factor is used to calculate the friction factor. Thus, the slip correction factor is about unity (1) for larger particles (Kn -> 0). Its behavior on the other end of the spectrum (smaller particles; Kn -> inf) is more nuanced, though it tends to scale linearly on a log-log scale, log Cc vs log Kn.
