Question 1.
What happens to air pressure when air velocity increases?
Show hintHide hint
Think about how airplanes use similar principles to generate lift.
Question 2.
What is Bernoulli's Principle about?
Show hintHide hint
Consider how it applies to wind turbines.
3Question 3.
What is Bernoulli's Principle?
- The principle that higher pressure leads to lower velocity
- The principle that higher velocity leads to lower pressure
- The principle that fluid flow is always smooth
Show hintHide hint
Remember what happens to air pressure in a jet stream.
4Question 4.
Does increasing wind speed always lead to increased energy capture?
- True
- False
Show hintHide hint
Think about how much energy a strong gust can produce compared to a light breeze.
Question 5.
A turbine design aims to maximize lift based on Bernoulli's Principle. If the blade angle is adjusted to create an optimal pressure drop, calculate how the lift would change with varying wind speeds.
Show hintHide hint
Consider how the lift force equation can integrate airflow changes.
Question 6.
Describe a situation where the turbine blades stall due to an adverse pressure differential and how that affects energy production.
Show hintHide hint
Reflect on the angle of attack and its impact on airflow.
