Solve the given question:
Question: The power available from a wind turbine is calculated by the following equation: P= (1/2)Apv^3. Where P=power [watts], A-sweep area(circular) of 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 410ft. the specific gravity of air is 0.00123.
Part A: Assuming a velocity of 30 miles per hour and an actual poet of 5.4 megawatts, determine the efficiency of this turbine.
Any help I can get on this question is greatly appreciated! I'm not too familiar with this question.
