Challenge Problems
Push your limits with advanced challenges
A wind turbine operates at an average wind speed of 6 m/s and has a Betz Limit of 59.3%. Calculate the theoretical maximum output if the turbine has an effective power coefficient of 0.4.
💡 Hint: Use the formula P = 0.5 * ρ * A * V^3.
Consider a wind farm with turbines designed to capture 50% of their potential energy at various wind speeds. How would you evaluate their efficiency when wind speeds change from 10 m/s to 20 m/s?
💡 Hint: Look at how doubling the wind speed impacts the energy output.
