Consider a wind turbine that is situated in an area that has steady winds. The turbine rotates at 16 RPM. The mass flow rate through the turbine is 41,025 kg/s. The tip velocity is 260 km/hr. Take the air density to be 1.31 kg/m² and assume 180kW of electric power is generated by the turbine. Determine the following: a. Average velocity of the air b. The efficiency of the turbine c. Assuming winds are steady for 95% of the year, is this a suitable location for a wind turbine? Explain.
A site is being considered for wind power generation. At this site, the wind blows steadily at 9 m/s for 2,579 hours per year. Assuming the wind velocity is negligible at other times for simplicity, determine the kWh/year that can be produced at the site for a turbine with a mechanical efficiency of 100% and an effective flow area of 5 m2. Use a value of 1.25 kg/m3 for the density of the air. Give your answer in killowatt-hours per year (kWh/year). Hint: I reccomend starting by finding the kinetic energy (kJ/kg) of the wind. Hint 2: Multiply the power generation (kW) by the number of hours of wind per year (h/year) to get kWh/year.
