Challenge Problems
Push your limits with advanced challenges
If a HAWT has rotor blades with a diameter of 80 meters and operates with a wind speed of 10 m/s, calculate the power output using the Betz limit (maximum efficiency of 59.3%). Use the formula: Power = 0.5 * ρ * A * v^3, where ρ is air density (approximately 1.225 kg/m³) and A is the swept area.
💡 Hint: Remember to use the three parts of the power equation and the Betz limit.
Discuss the environmental implications of siting a HAWT in a migratory bird path. What factors should be taken into account?
💡 Hint: Consider the potential dangers to wildlife from turbine placement.
