I'd like to pin > down the reason I'm getting a different result than you. Rearranging drag = dynamic pressure * coefficient * area to give dynamic pressure = drag / (coefficient * area). I used coefficient on the order of 1, area 1.5 m^2, and drag 20 kN to get 13 kPa, then allowed about 50% margin for the harder to model variation of forces over the sphere. - Tim
