Wind turbine produces 8MWatts
(If wind speed is proportional to the 7th root of altitude)
(Wind power is proportional to the cube of wind speed
First the turbine is at 450ft then reconstructed at 650ft, how much faster is wind speed? and how much more power?
Sw= 7√Altitude, Pw= (Sw)3

Im not sure if a value is being asked? so this is what I tried to do.
a. 7√450 =2.39 and 7√650 =2.52 ,then output/input , so 2.39/2.52 =.948 or
95% more?

b. (2.39)3=13.6 and (2.52)3=16 , so 13.6/16 =.85 or
85% more?
