I personally don't like windy days. However, the wind could help us more than we think. We could use the wind to produce energy. This is what wind turbines do and I will now research them to determine the physics involved and how they work, their history, along with some statistics from the US. Then I'll delve into wind turbines in Texas, Washington, and Kansas and compare them. The Physics of Wind Turbines There is physics involved in these wind turbines as they transform wind into mechanical energy and then into electricity. The energy produced depends on the volume of the air, the density and the speed of the wind. Mass per unit time is mass times density times wind speed or m = mass, p = density, A = area, and v = wind speed; m = pAV. Since the function of the wind turbine is to transform the kinetic energy of the wind into electricity, the equation for kinetic energy is needed; KE = ½ mv2 or kinetic energy equal to half the mass times the velocity squared. So, using substitution, the wind power depends on the density of the air, the area swept by the rotors and the cube of the speed or ½ pAV3. Using Betz's law the theoretical energy model to extract 59% of the energy is power = 16/27(½ pAV3). The power that passes through or is created by wind energy is ½ pAv3. However, all the power cannot be captured, because that would mean that the wind would have to be still, absolutely absent, which is impossible when the wind starts the whole process. Therefore, it is necessary to find the theoretical maximum power. To find the horsepower, take the kinetic energy through the wind turbine minus the kinetic energy out. So, using three different areas, you can find the constant rate of... half of the paper... published August 11, 2009, cited October 3, 2010]. [about 5 paragraphs].
