Propeller RPM and Weight of Craft
Status: student, student

Is there any relation between RPM of the propeller of an airplane and the weight of craft?
There is no relationship at all between an airplane's weight and the
RPM of its propellers. Propellers may be designed for highest thrust, in
which case they are operated at an RPM that results in their tip speed
approaching (but not exceeding) the speed of sound. On the other
hand, if maximum efficiency is required, they are operated at a
generally lower RPM that results in optimal efficiency.
