- Wind power is defined as the use of air flow through wind turbines to provide the mechanical force to generate electricity. Wind power is an alternative to burning fossil fuels, and is renewable and produces no greenhouse gas emissions during operation. Modern horizontal-axis wind turbines often use three blades. Theoretically, the maximum power P (unit: watts) that a three-blade wind turbine can extract from the wind power can be calculated as: P = pAv³C₁. . (Equation 1) where p is the air density (kg/m³), A is the sweep area of the turbine (m²) and can be calculated from the length of the turbine blades, and v is the wind speed (m/s). Cp is the power coefficient that is unique to each turbine type. This coefficient represents the amount of kinetic energy from the wind that is captured by the turbine. From the Betz's limit law we know that the best power conversion possible is Cp,max = 0.59. Part 1 Given the following data: Blade length /= 50 m Air density p= 1.5 kg/m³ Power…DS Community Downl...
