RPM vs propeller pitch

G'day All..
I have a question:
A particular engine is supposed to develop between 2800 and 3000 static RPM with a given prop. If I have a ground adjustable prop of the appropriate diameter (as in, according to the POH), how many RPM will be lost with every 1" increase in pitch? Just looking for a ballpark figure here..
