Some benefits to solar power:
Isolated power is very abundant on earth.
Is very sustainable (5 billion years of good use)
Eco friendly excluding panel production.
Some disadvantages:
Very expensive to set up
Takes up a lot of space per person
Requires exotic materials to construct
Energy storage is difficult with solar cells compared to fossil fuels.

butalik [34]

Answer:        

Number of turns in secondary will be 7

Explanation:

We have given primary voltage V_p=120volt

Number of turns in the primary is N_p=3575

Secondary voltage is given V_s=235mV=0.235volt

We have to find the number of turns in secondary

We know that \frac{N_p}{N_s}=\frac{V_p}{V_s}

So \frac{3575}{N_s}=\frac{120}{0.235}

N_s=6.60

As the number of turns can not be in decimal so number of turns will be 7

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}.
