Plotting Power and Torque Curves.
The table below is from Gordon Cornell's book. Using the P and K factors given and the RPM figures a Power versus RPM, and Torque versus RPM curve can be easily drawn. The propeller sizes do go up to 12x6" so the curves for reasonably large diesels can be examined. I believe that this Table is used by engine testers whose work in regularly published in ACLN and The Aeromodeller.
The equations for each of the data points are:
BHP=P x RPM^3
OR
TORQUE = K x RPM^2

APC also have calculated values for their props here; https://www.apcprop.com/v/PERFILES_W...tDatafiles.asp
