Q9: Salalah city is planning to install a 3.0 MW wind turbine. The turbine has a 112 m rotor diameter and the
power/speed curve shown in Figure Q9. During the daytime hours (7am to 7pm) the wind speed is 12 m/s and the
cost of electricity is $100/MWh. During the nighttime hours the cost of electricity is $50/MWh and the wind speed is 6
m/s. Assume that the air density is constant at 1.2 kg/m³.
Determine the power output, wind power input, and efficiency of the turbine/generator during the daytime hours.
Determine the power output, wind power input, and efficiency of the turbine/generator during the nighttime hours
Calculate the daily revenue that the plant earns from selling electricity.
