Determining the Power Density and the Available Power of a Wind Farm
The elevation of a wind farm is 320 m. There are three rotating blades of the wind turbine and each blade is 12 m in length with a sweep diameter of 24 m. If the air temperature is 30°C and the speed of the wind is 10 m/s, calculate (a) the air density δ, (b) the power density ρ, and (c) the available power from the wind.
