EF 152 – Physics for Engineers Spring, 2009 Recitation 6.1 Wind Speed and Power Measure the wind speed of the fan using the anemometer. It is suggested that the wind speed be measured at several different locations to find the best location for your generator. From the wind speed, calculate the theoretical power going into your windmill generator. Remember, power is energy per time. The kinetic energy of the air is:

Unformatted text preview: 2 2 1 mv KE = Rewrite the mass in terms of density and volume, where the volume is the cross-sectional area multiplied by a length. 2 2 2 1 2 1 ALv mv KE air = = Power is work divided by time. What is L/t? From this, you can calculate the power coming into your generator from the air. A good link for further information is http://www.awea.org/faq/windpower.html...
