Question

Please assume the wind speed at a height of h = 10 misu = 9 Using the wind speed-altitude power law with an exponent of n = 0.2 please calculate the height at which a wind speed of 10 m/s is available.

Answer 1

Power law :-

$\frac{u}{u_r} = {(\frac{h}{h_r})}^n$

where,

u :- Wind speed at height h

ur :- known Wind speed at reference height hr

Given :-

  

To find :-

Solution :-

$\frac{10}{9} = {(\frac{h}{10})}^{0.2}$
