The wind velocity at 32 m above the ground is 6.39m/s when the roughness exponent of the surface is 0.23
Given in the problem is
Wind velocity at 13m above the ground v1 =5.2 m/s
Height initially h1 = 13m
height at which wind velocity is to be predicted h2= 32m
surface roughness exponent α = 0.23
Let velocity to be predicted be v2
We know that from the formula
v2= v1*(h2/h1)^α
⇒v2= 5.2 * (32/13)^ 0.23 = 6.39 m/s
Thus the wind velocity at 32m above the ground is 6.39m/s
