Sweep area of the turbine (HAWT):
\[ A = \pi \times L^2 \]
Sweep area of the turbine (VAWT):
\[ A = D \times H \]
Available wind power:
\[ P_{wind} = 0.5 \times \rho \times v^3 \times A \]
Efficiency of the turbine:
\[ \mu = (1 - k_m) \times (1 - k_e) \times (1 - k_{e,t}) \times (1 - k_t) \times (1 - k_w) \times C_p \]
Output power:
\[ P_{output} = \mu \times P_{wind} \]
