Question: Wind ( = 1.204 kg/m 3 ) blows through a HAWT wind turbine. The turbine diameter is 45.0 m. The combined efficiency of the gearbox

Wind (ρ = 1.204 kg/m³) blows through a HAWT wind turbine. The turbine diameter is 45.0 m. The combined efficiency of the gearbox and generator is 88 percent.

(a) For a realistic power coefficient of 0.42, estimate the electrical power production when the wind blows at 7.8 m/s.

(b) Repeat and compare using the Betz limit, assuming the same gearbox and generator.
