    The exponents of the clearance to radius term (CR) 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)12(ρoρd)12ΛReCμL2ρdC3(ΩR)
    19
    and 
    ζ(LD)2(CR)1(Δppo)12(ρoρd)12Λ12ReC12.

    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 (LD)2, (CR)1, and …”.
