Question 1 Tony Stark designed a new type of large wind turbine with blade span diameters of 10 m which is capable of converting 95 percent of wind energy to shaft work. Four units of the wind turbines are connected to electric power generators with 50 percent efficiency, and are placed at an open area at a point of 200 m height on the Stark Tower, with steady winds of 10 m/s during a 24-hour period. Taking the air density as 1.25 kg/m?, 1) determine the maximum electric power generated by these wind turbines; and (8 marks) 11) determine the amount of revenue he generated by reselling the electricity to the electric utility company for a unit price of $0.11/kWh.
