Torque Measurement in Wind Turbines HBM

The output of a rotating body is obtained from the product of torque and angular speed. P = Output in N•m/s (1N•m/s = 1 W = 0.00136 metric hp) M = Torque in N m ω = Angular speed in s-1 N = Rotational speed in rpm. Transformation and some other steps give the relationship for torque

WIND TURBINE POWER, ENERGY, AND TORQUE

2013-9-4  At standard conditions, the power in 1 m2 of wind with a speed of 5 m/s is 0.647(5)3 = 81 W. The power in the same 1 m2 of area when the wind speed is 10 m/s is 647 W. This illustrates two basic features of wind power. One is that wind power is rather diffuse. It requires a substantial area of wind turbine to capture a significant amount of power. The
