There's a lot of things that determine prop slip. Pitch, Cupping, Rake, Material, Diameter, Number of blades, Leading edge, Trailing edge, Blade tip, Blade root just to name a few.
A good quick way to determine what is your prop slip is to use this calculator from Mercury Racing. While it may not be accurate for a racing enthusiast, it's more than sufficient for the average Joe.

If God didn't have a purpose for us we wouldn't be here, so
Live simply, Love generously, Care deeply, Speak kindly.

Silence, in the face of evil, is itself evil. Not to speak is to speak, not to act is to act. God will not hold us guiltless.
