y Estimating output from a turbine: the following data for a large turbine designed for high-wind areas is provided. The turbine swept area has a diameter of 80 m and you can assume an air density of 1.15 kg/m3. In the data below, bin 1 spans from 0 m/s up to the cut-in speed of 6.25 m/s, and thereafter each bin spans a 0.5 m/s increment, for example, bin 2 is 6.25 to 6.75 m/s, and so on. Bin 17 spans from 13.75 to 25 m/s, and above 25 m/s the machine stops (i.e., this is the cutout speed). The device is being considered for use in a site with average wind speed of 9.6 m/s. (Data source: ASME Table 5-1 from ASME Press, "Wind Turbine Technology: Fundamental Concepts of Wind Turbine Engineering," David Spera, Page 22) BIN PoUT kW UAVGa. Plot Cp for the turbine as a function of bin number, using the Vavg value for each bin as a basis for calculating power in the wind. (Include the Betz limit on the plot for reference.) b. Calculate the predicted total annual output and capacity factor for this device in the chosen location, using the site average wind speed and assuming the wind follows a Rayleigh distribution. CONSIDER CHANGING VALUES SO AVERAGE POWER/PEAK POWER WILL NOT BE THE SAME AS CAPACITY FACTOR c. Based on (b), is the device suitable for the site?
