Spin factor = Angular Velocity * radius / velocity

Coefficient of lift = -0.05 + sqrt(0.0025 + 0.36 * radius * abs[angular velocity/velocity])

I've seen angular velocity in rpm or rad/s or...

I've seen velocity in mph or m/s or...

I've seen radius in inches or meters or...

The Coefficient of lift formula is taken from this paper.

The Spin factor from this paper.

If I get the proper units it should provide a graph with similar results to these. Left coefficient of lift, bottom spin factor.

If you know of better research papers or source code, I would love a link.

An example problem would also be very helpful.

Thanks
