Explanation:
Please kindly check attachment for the step by step solution of the given problem.
Solution :
Given :

Operation time,
= 3000 hours per year

Operation time,
= 2000 hours per year
The density, ρ = 
The wind blows steadily. So, the K.E. = 

The power generation is the time rate of the kinetic energy which can be calculated as follows:
Power = 
Regarding that
. Then,
Power
→ Power = constant x 
Since,
is constant for both the sites and the area is the same as same winf turbine is used.
For the first site,
Power, 

For the second site,
Power, 
Answer:d
Explanation:
Given
Temperature
Also 
R=287 J/kg
Flow will be In-compressible when Mach no.<0.32
Mach no.
(a)
Mach no.
Mach no.=0.63
(b)
Mach no.
Mach no.=0.31
(c)
Mach no.
Mach no.=1.27
(d)
Mach no.
Mach no.=0.127
From above results it is clear that for Flow at velocity 200 km/h ,it will be incompressible.
