Figure 5.16.12 shows a plot of drag S versus w. Equation 5.16(41) assumes that the increase in drag with increasing areal density is linear; however, the increase is linear only after a dust cake has formed. Therefore, Equation 5.16(41) can be rewritten as follows in terms of the extrapolated residual areal dust density after cleaning wR and the effective drag SE.
