13-3. Apply the power curve of Fig. 13-14 to a site with average wind speed of U = 7.7 m/s, with bin speed estimated using a Rayleigh distribution. Using 0.5 m/s bin size increments, estimate total output from the device in this location in kWh and the capacity factor. 13 u a small turbine rated at 10 kW has approximately the following power curve: kW; 4 m/s<U≤ 10 m/s, P = (10/6)(U-4) kW; 10 m/s≤ U <20 m/s, P=10 kW;
