$$ Determine the settling velocity for hookworm eggs which have a diameter of $60$m$,$ density of $1\mathrm{.}055$ g$/$cm$3$ and assumed spherical shape. Assume the wastewater temperature is $15$C$.$ Assume $=1\mathrm{.}14010-3$ N$-$S$/$m$2$ and the density of water equals $999\mathrm{.}1$ kg$/$m$3.$
