v(h) = v₁₀ × (h / 10 m)^α
Power-law wind profile; α = 0.14 is an approximate open-meadow shear exponent.
Pₑ = ½ ρ A v³ Cₚ η, where A = π(D/2)².
Uses air density ρ = 1.225 kg/m³, assumed power coefficient Cₚ = 0.38, generator efficiency η = 0.92 and each turbine's nominal rotor diameter.
Limitations: steady, horizontally uniform wind; no turbulence, wake losses, direction changes, blade pitch control, cut-in/cut-out behaviour or rated-power clipping. This is an educational estimate, not a forecast or engineering yield calculation.
