An engineer is considering the development of a small wind turbine (D = 1.25 m) for home applications. The design wind speed is 15 mph at T = 10°C and p = 0.9 bar. The efficiency of the turbine is η = 20%, meaning that 20% of the kinetic energy in the wind can be extracted. Estimate the power in watts that can be produced by the turbine. Hint: In a time interval Δt, the amount of mass that flows through the rotor is Δm =m· Δt, and the corresponding amount of kinetic energy in this flow is (ΔmV ²/2).
