Hey guys, so I'm building a mini wind tunnel and I would like to calculate the new RPM,HP and Torque since the propeller will act as a load and change the specs of the motor(note I'm using a air wrench as the motor as it's all I had around and have disabled the impact motion) the current specs are 1,000HP 750ftlbs torque and 9500rpm the shaft diameter is 1/2 in and the propellers. Weight is 9lbs and is 45in in diameter I'm looking to find out how the propellers weight will affect HP,Torque and RPM...thanks
