A fat globule of 1.5 \mum diameter is rising up in a stagnant skim milk medium of $1005 \mathrm{~kg} \mathrm{~m}^{-3}$ density and $1.5 \mathrm{cP}$ viscosity. If the density of the fat globule is $915 \mathrm{~kg} \mathrm{~m}^{-3},$ the steady rising velocity of the globule in $\mu \mathrm{m} \mathrm{s}^{-1}$ is_____________
