Question 1.
What is the main difference between HAWTs and VAWTs?
Show hintHide hint
Think about the orientation of the blades.
Question 2.
Name one advantage of VAWTs.
Show hintHide hint
Consider their design.
3Question 3.
What type of wind turbine is generally more efficient?
- HAWT
- VAWT
- Both
Show hintHide hint
Recall which turbine is used in large farms.
4Question 4.
True or False: VAWTs require yaw systems to orient themselves to the wind.
- True
- False
Show hintHide hint
Consider how each turbine type is designed.
Question 5.
Design a hypothetical wind farm using both HAWTs and VAWTs. Explain the rationale for using each type in different areas of the farm.
Show hintHide hint
Consider wind patterns in both open and urban areas.
Question 6.
Calculate the potential energy output difference between a HAWT and a VAWT given specific average wind speeds and efficiencies.
Show hintHide hint
Use the formula for wind power: P = 0.5 * ρ * A * v³, where ρ is air density, A is swept area, and v is wind speed.
