Table 2.2 gives the wind data for a site in terms of the percentage of time over a year for different speed groups Calculate the annual average power in the wind passing normally through the swept area of a turbine of diameter 30 m. Take 1.225 kg/m² as the density of air. Table 2.2 Speed group (m/s) 053 356 659 9512 12ces16 16 <20 Percentage 12.36 29-25 of time 29.37 18.96 9.31 1.67 Table 2.2 gives the wind data for a site in terms of the percentage of time over a year for different speed groups Calculate the annual average power in the wind passing normally through the swept area of a turbine of diameter 30 m.
