An industrial wind turbine has blades that are 35 m long. On a 20?C day, wind at atmospheric pressure blows with a velocity of 12 m/s
An industrial wind turbine has blades that are 35 m long. On a 20?C day, wind at atmospheric pressure blows with a velocity of 12 m/s , and wind in the turbine wake only has a velocity of 11 m/s .
(a) If we assume that all of the kinetic energy lost by the wind is converted to electrical energy by the turbine, then what is the power generated by this turbine? (density is 1.205 kg/m^3)
(b) This turbine is rated as a 1.5 MW turbine. If we assume the turbine’s wake is always 1 m/s slower than the ambient wind speed, then how fast would the wind have to be blowing to generate the full 1.5 MW?

A typical wind turbine extracts 40% of the kinetic energy of the wind that blows through the area swept by the blades. For a large turbine, 110,000 kg of air moves past the blades at 15 m/s every second. If the wind turbine extracts 40% of this kinetic energy, and if 80% of this energy is converted to electric energy, what is the power output of the generator?

QUESTION 5 A wind turbine is operating in a wind of 10 m/s - that has a density of 1.2 kg/m3. The diameter of the windmill is 4 m. The constant pressure_ (atmospheric) streamline passing the turbine blade tip has a diameter of 3 m upstream of the wind turbine and 4.5 downstream. Assume that the velocity distributions are uniform and the air is incompressible. Determine the thrust due to the wind on the wind turbine. (5 marks)
