2. Wind Turbines
Wind power is a renewable and cheap source of energy similar to solar power. In fact it is mainly caused by solar energy.
Wind power industry using wind turbines is clean with a fast growth in technology and demand.

3. Today's Learning Objectives
After today's class, students will be able to:
Describe the relationship between wind velocity and air pressure based on Bernoulli’s Equation for an incompressible flow
Calculate the energy available in the wind and compare it to the power generated by a wind turbine
Slide was okay

4. Bernoulli’s Principle
Bernoulli’s principle states that for an ideal fluid (like air), an increase in velocity occurs with a decrease in pressure of that fluid.
Bernoulli’s equation for incompressible fluid flow is described as:
𝑣 𝑝 1 𝜌 +𝑔 𝑧 1 = 𝑣 𝑝 2 𝜌 +𝑔 𝑧 2
In order to harness wind energy efficiently, air foil design must maximize lift and minimize drag.

Slide on Bernoulli’s ?
Wind Turbine Lab Setup

6. Tips for a Successful Lab
The radius is 0 cm is when the pitot tube is at the center of wind tunnel (use the notches on the tube as a guide).
Remove the propeller if it is mounted on the generator at the beginning of the lab.
Only the first speed in the Arduino display panel is used in this lab.

7. Important Takeaways
Wind turbines can convert mechanical energy (from the wind) into usable electricity
Bernoulli’s principle and equation describe the relationship between velocity and pressure in fluid flow
There are several parameters that influence the amount of power generated by a wind turbine.
This was revised to be a takeaway slide, specifically a summary of important concepts from pre-readings and the lab procedure
