Thank you for the reply minger & Dr.D
The 120 lbft force is what I observed without my device moving (no angular velocity). 15 rpm is the ideal rotational speed due to the mechanical nature of my prototype.
My intuition tells me to calculate the difference between wind speed and paddle...
I made a wind generating device that produces 120 lbft static torque with a 30mph wind. The paddles that interface the wind have rotational center of 4.5ft(radius). My device will be rotating at 15rpm. How do I calculate how much power is produced at any given wind speed?
