where. p = air pressure, T = temperature on the absolute scale, and. R = gas constant. The air density at sea level at 1 atm ( psi) and 60°F is kg/m 3. Using this as a reference, p is corrected for the sitespecific temperature and pressure. The temperature and the pressure both vary with the altitude.

Area = ∏r2 P = 1/2 x ρ x A x V Being able to measure the swept area of your blades is essential if you want to analyze the efficiency of your wind turbine. The swept area refers to the area of the circle created by the blades as they sweep through the air. To find the swept area, use the same equation you would use to find the area

A Swept area Air Density (1) A physical limit exists to the quantity of energy that can be extracted, which is independent of design. The energy extraction is maintained in a flow process through the reduction of kinetic energy and subsequent velocity of the wind. The magnitude of energy harnessed is a function of the reduction
