V = IR

By completing the equation, i found that the total power equation is : 4.8, 
Which means that it's not exceed the power rating.

So i believe the answer would be :  The string will remain lit

At a certain location, wind is blowing steadily at 10 m/s. Determine the mechanical energy of air per unit mass and the power ge
Damm [24]

Answer:

0.05\ \text{kJ/kg}

3141.6\ \text{kW}

Explanation:

v = Velocity of wind = 10 m/s

A = Swept area of blade = \dfrac{\pi}{4}d^2

d = Diameter of turbine = 80 m

\rho = Density of air = 1.25\ \text{kg/m}^3

Wind energy per unit mass of air is given by

E=\dfrac{v^2}{2}\\\Rightarrow E=\dfrac{10^2}{2}\\\Rightarrow E=50\ \text{J/kg}

The mechanical energy of air per unit mass is 0.05\ \text{kJ/kg}

Power is given by

P=\rho AvE\\\Rightarrow P=1.25\times \dfrac{\pi}{4}\times 80^2\times 10\times 50\\\Rightarrow P=3141592.65=3141.6\ \text{kW}

The power generation potential of the wind turbine is 3141.6\ \text{kW}.
