The meteorite weighs 0.025kg, and has the speed 28.6km/s 50km vertically above the surface of the earth, giving it a Reynolds number of approximately 3.5*10^7.

The quadratic drag equation, F_d = 0.5*p*C_d*A*v^2, is used for Re > 1000.

My question is: Will this equation still give a reasonable approximation of the drag, experienced by the meteorite, or do you know of any other equations used at such high Reynold numbers and speeds?

Thanks!
