2 cards from this section. Quick, good the night before a test.
What causes wind?
Think about temperature differences.
What is the Betz Limit?
It’s a percentage based on kinetic energy.
What is the main cause of wind?
Remember how temperature affects air movement.
True or False: The Betz Limit states that a wind turbine can capture all kinetic energy.
Consider the theoretical limits of efficiency.
Calculate the potential energy output of a wind turbine located in a region with an average wind speed of 10 m/s and a rotor area of 100 m². Use the formula for power output: P = 0.5 * ρ * A * V^3, where ρ (air density) is approximately 1.225 kg/m³.
Consider using the wind power formula directly.
Discuss the trade-offs between horizontally and vertically oriented wind turbines when placed in urban areas. What factors would influence your decision?
Think about location, efficiency, and maintenance.
