Cunningham slip 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. WebHere cc is the Cunningham slip correction factor given in Table 2.2. It should be included when rp is comparable with the mean free path of the gas molecules. Data from inertial …
