A small horizontal-axis wind turbine (HAWT) is being designed to deliver 2 kW shaft power at a steady wind speed of 7 m.s−1. The HAWT operates with an aerodynamic power coefficient of 0.36, drivetrain efficiency of 0.90, and air density of 1.225 kg.m−3. Neglecting other losses, the required rotor diameter is X m.
When the wind speed drops to 6 m.s−1, the shaft power is Y kW. Identify the nearest correct option for X and Y combination
(Take π = 3.14)
