I'm trying to calculate Stoke's drag constant using the equation found here.

The system I wish to calculate it for is a mass oscillating vertically on a spring through air. The temperature is 25 degrees celsius. The area of the base of the mass is 4.9x10^-4 square metres.

I'm not sure how to find the 'fluid viscosity' in the linked equation, or what 'Stoke's radius' is.

From where, MathsStudent, do You get the idea, that Stokes law is appropriate to Your "spring"? Did You check Reynolds Number? –  Georg May 21 '11 at 10:24
