Numerical Problems on How to find renewable energy

Problem 1:

A wind turbine has a rotor diameter of 80 meters and is placed on a site where the average wind speed is 10 meters per second. Assuming the air density is 1.2 kg/m³, calculate the maximum theoretical power output of the wind turbine.

Solution:
The maximum theoretical power output of a wind turbine can be calculated using the formula:

$P_{\text{max}} = \frac{1}{2} \times \rho \times A \times v^3$

where:
– $P_{\text{max}}$ is the maximum theoretical power output,
– $\rho$ is the air density,
– $A$ is the swept area of the turbine (area covered by the rotating blades),

Given:
– $\rho = 1.2$ kg/m³ (air density),
– $A = \pi \times \left(\frac{d}{2}\right$ ^2 ) (swept area of the turbine),
where $d$ is the rotor diameter,
– $v = 10$ m/s (wind speed).

Substituting the values into the formula:

$P_{\text{max}} = \frac{1}{2} \times 1.2 \times \pi \times \left(\frac{80}{2}\right)^2 \times 10^3$

Simplifying:

$P_{\text{max}} = 0.6 \times 1.2 \times \pi \times 40^2 \times 10^3$

Calculating:

$P_{\text{max}} \approx 904,778 \, \text{kW}$

Therefore, the maximum theoretical power output of the wind turbine is approximately 904,778 kW.

Substituting the values into the formula:

$P_{\text{max}} = 0.18 \times 2.5 \times 800$

Calculating:

$P_{\text{max}} = 360 \, \text{W}$

Therefore, the maximum power output of the solar panel is 360 W.
