At a certain location, wind is blowing steadily at 10 m/s. determine the mechanical energy of air per unit mass and the power generation potential of a wind turbine with 90-m-diameter (d) blades at that location. take the air density to be 1.25 kg/m3.

e= 50 J/kg

Explanation:

Given that

Speed ,v= 10 m/s

Diameter of the turbine = 90 m

Density of the air ,ρ = 1.25 kg/m³

We know that mechanical energy given as

That is why mechanical energy per unit mass will be

Now by putting the values in the above equation we get

e= 50 J/kg

That why the mechanical energy unit mass will be 50 J/kg.

answer:

c
