The exponents of the clearance to radius term $(C∕R)$ in the scaling law for damping ratio $ζ$ in Eqs. 19,20 were inadvertently switched between these two equations. Equations 19,20 should read:
$ζ∝(CR)−3(Δppo)−1∕2(ρoρd)−1∕2ΛReCμL2ρdC3(ΩR)$
19
and
$ζ∝(LD)2(CR)−1(Δppo)−1∕2(ρoρd)1∕2Λ1∕2ReC−1∕2.$

This correction also pertains to Table 1, where the second term in the last row, with the damping ratio $ζ$, should read $−1$ as shown below.

Consistently, the second sentence of the fifth paragraph on p. 259, in the section “Design Implications,” should read: “Since the damping ratio $ζ$ scales with $(L∕D)2$, $(C∕R)−1$, and …”.
