Below is what I have always used to calc prop slip:
RPM X Prop pitch =
1056 x gear ratio =
Example:
6500 rpm x 28 pitch = 182,000
1056 x 1.75 = 1848
182,000 divided by 1848 = 98.48 mph "theoretic speed" sub track actual gps speed from theoretic speed and thats the % or efficiency loss.
So I came into this post a little late. My numbers are greatly off, as I come up with a neg number. -1.62???
21.5 pitch
5800 rpms
48 mph
2.50.1 gear ratio
