Consider creeping flow of a sphere of diameter \(D\) moving through a fluid at speed \(V\). We gave an expression for drag force, \(F_{D}=3 \pi \mu V D\). The drag coefficient \(C_{D}\) over three-dimensional bodies is typically defined as \(C_{D}=\frac{F_{D}}{\frac{1}{2} ho V^{2} A}\) where \(A\) is the frontal area of the body (the area you "see" when looking at the body from upstream). Generate an expression for \(C_{D}\) in terms of Reynolds number for this flow.
