## Main Question or Discussion Point

Hi,

I'm looking for a correlation of the drag force on a cylinder in parallel creeping (stokes') flow (i.e. the flow is alongside the axis of the cylinder). My length-to-width ratio is such that assuming an infinitely long cylinder is perfectly okay.

Does anyone know where I can find such a correlation?

I've tried deriving it myself but I ran into something called the Stokes' paradox. I know this can be solved by an approximation method (taking a linear inertia term into account), but I do not want to dive in that deep, I just need the equation for a calculation.
