   Renpen got the RPM correct. Now if you want to figure the speed of the tip in miles per hour you need to know the length of the blade. Then you need to do the 2piR=C thing and a little math, you’ll know how fast it can throw a rock through your picture window. RScott

   Same speed as the engine is turning. 3000 to 3500 RPM.
