Is there one published or has anyone ever compiled a chart that list the speed that one should get from a given prop configuration. Such as:
--------PITCH--------
RPM 48 49 50 51 52
2100 81 83 85 86 88
2150 83 85 87 88 90
2200 85 87 89 90 92
2250 87 89 91 92 94
2300 89 91 93 94 96
2350 91 93 95 96 98
2400 93 95 97 99 100
2450 95 97 99 101 103
2500 97 99 101 103 105
2550 99 101 103 105 107
I understand that the numbers can't
be exact, due to variations in
airframe. However, it would give
a good indication of what should be
obtained by changing a prop.
If anyone has one, or the calc. for
building a chart, I would like a copy.

P.S.: The chart above is my best guess.
Pitch * RPM * .85 (eff). Converted to MPH
