Think of the prop as working like a wood screw, where a prop with a 17" pitch travels 17" for each revolution if there was NO slip. Add gear ratio, engine rpm and throw some constants into the equation to convert minutes to hrs and inches to miles and you can come up with a theoretical mph (with NO slip) for a given rpm. The % difference between the theoretical and actual mph at the same rpm is slip.
