In a place where a wind farm is installed, the wind has an average speed of 5.5 m/s and generators with 65 m blades are used. Determine the number of generators needed to generate 39 M Watt. The density of air is 1.23 Kg/m3
Added by Amparo B.
Step 1
5 * density of air * area swept by the blades * wind speed^3 Given: Density of air = 1.23 Kg/m^3 Blade length = 65 m Radius of the swept area = 65 m Area swept by the blades = π * (65)^2 = π * 4225 ≈ 13273.24 m^2 Wind speed = 5.5 m/s Power = 0.5 * 1.23 * 13273.24 Show more…

At a certain location, wind is blowing steadily at $10 \mathrm{m} / \mathrm{s} .$ Determine the mechanical energy of air per unit mass and the power generation potential of a wind turbine with 60 -m-diameter blades at that location. Take the air density to be $1.25 \mathrm{kg} / \mathrm{m}^{3}$
A wind turbine with a blade diameter of 95 m is designed to produce 4.5 MW with a wind speed of 13 m/s. Estimate the power coefficient for this wind turbine. Assume an air density of 1.225 kg/ m3.
