For the following operating conditions:

Gas density ${}_g=3\mathrm{.}708l\frac{b}{f}{t}^2$

Gas viscosity ${}_g=0\mathrm{.}013cP$

Oil density ${}_o=53\mathrm{.}03l\frac{b}{f}{t}^3$

Oil droplet diameter $d_m=100$ microns

Assume initial $C_D=0\mathrm{.}44$

CALCULATING DRAG COEFFICIENT C $($An Iterative Procedure$)$

Assume initial value for $C_D$

Calculate settling velocity $u$

Calculate Reynolds Number Re

Calculate $C_D,$ and compare with to assumed $C_D$

If no match is obtained, use calculated $C_D$ and repeat steps $2-4$ until convergence is obtained.

Settling Velocity:

$u=0\mathrm{.}01186[(\frac{{}_o-{}_g}{{}_g})\frac{d_m}{C_D}{]}^{\frac{1}{2}}f\frac{t}{s}$

Reynold's Number:

$Re=0\mathrm{.}0049\frac{{}_g{d}_{m}u}{{}_g}$

Drag Coefficient:

$C_D=0\mathrm{.}44+\frac{3}{R{e}^{0\mathrm{.}5}}+\frac{24}{Re}$
