Answer:
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.
