Question Help ▼ The power available from a wind turbine is calculated by the following equation: P= where P= power [watts], A=sweep area (circular) of the blades [square meters], p= air density [kilograms per cubic meter], and v=velocity [meters per second]. A wind turbine generator has a blade diameter of 380 feet [ft]. The specific gravity of air is 0.00123. Assuming a velocity of 32 miles per hour [mi/h] and the power produced is 4.8 megawatts [MW], determine the efficiency of this turbine. E Click the icon to view the conversion table for length.
