Question

Calculate the total power density in the wind stream with the given data:density of air = 1.226 kg/m3, velocity of wind = 10 m/s, atmospheric pressure = 1.​

Answer 1

Explanation:

We are given the following data: Blade length, l = 52 m. Wind speed, v. = 12 m/sec. Air density, ρ = 1.23 kg/m3. Power Coefficient, p. C.

Answer 2

Answer:

The total power density in the wind stream is 613 watts per square meter.

Explanation:

Given:

The density of air $= 1.226\:kg/m^{3}$

The velocity of the wind $= 10 \,m/s$

Atmospheric pressure $=1$

We know that,

Wind power density $= \frac{1}{2} \times$ air density of the site $\times$ wind speed cubed

Wind power density:

$=\frac{1}{2} \times 1.226\times10\times10\times10\\=613\text { watts per square meter }$

Therefore, the total power density in the wind stream is 613 watts per square meter.
