How Do You Calculate Thrust Of A Propeller With Rpm?

How Do You Calculate Thrust Of A Propeller With Rpm? Where power is in watts and rpm is in thousands. For example, a 6X4 APC propeller has a propeller constant of 0.015 and a power factor of 3.2. Given a rotational speed of 10,000 rpm, the calculation goes as follows: Power=0.015X103.2=24 W. The next step
