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 there asking for a value or %, so this is what I tryed.
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?
