There is a wind turbine close to the shoreline. The turbine capacity is 3 MW, the rotor diameter is 90 meters, and tower height is 110 meter. The Cp is 43.7%. The yearly average wind speed at 10 m is 5.5 m/s. There is a potential to move the machine to a 120 meter tower. How much power is in wind at 110 & 120m height at the site? (Use the power law for wind speed calculation)

For this problem, consider a site which is experiencing a wind speed of 9.5 m/s. You are to calculate how much power there is in the wind in Watts at this moment as it flows through the rotor of a wind turbine. Please assume that the air temperature is 14 degrees C at hub height conditions and the pressure can be considered to be 99.78 kPA for a rotor diameter of 32 m. (answer to 0 decimal places)

The state of Iowa is among the top three states in U.S. in wind power generation. In 2016, over 20 billion kWh of electrical energy in Iowa was generated by wind power. Assuming that wind speed at the altitude of wind turbine is in average of 6 m/s, the efficiency of converting wind energy to the electricity is 80 %, and all wind turbines work constantly throughout the year. We can further assume that the air in Iowa has an...
