Wind Power in the United States Essay -- The Physics of Wind Turbines

I personally do not like touchy days. However, wind could be helping us much than we realize. We could be using the wind to produce energy. This is what wind turbines do and now I will be researching them to determine the physics involved with them and how they work, their history, along with roughly statistics from the United States. Then I will go in-depth for the wind turbines of Texas, Washington, and Kansas and compare them.The Physics of Wind Turbines There is physics involved in these wind turbines as they change wind into mechanical energy and then into electricity. The energy produced depends on the volume of the air, the denseness, and the wind speed. The mass per unit time is the mass quantify the density times the wind speed or m = mass, p = density, A = area, and v = wind speed m = pAV. Because the function of the wind turbine is to transform the winds kinetic energy into electricity the equation for kinetic energy is needed KE = mv2 or kinetic energy equals one ha lf the mass times the velocity squared. Then, using substitution, the strength in the wind depends on the density of the air, area swept out by rotors, and the cube of the velocity or pAV3. using Betz law the theoretical energy model for extracting 59% of the energy is power = 16/27( pAV3) .The power passing through or created by the wind power is pAv3. All the power cannot be captured though, because that would mean the wind had to be still, absolutely no wind, which is impossible when the wind starts the whole process. Thus, one needs to find the level best theoretical power output. To find the power, take the kinetic energy in through the wind turbine minus the kinetic energy out. Then using deuce-ace different areas one can find the constant rate of ... ...issued on 2009 Aug 11, cited 2010 Oct 3. about 5 paragraphs.
