Renewable energy. Wind. A wind turbine with a blade diameter of 21 m is to be installed in a location where average wind velocity is 5.6 ms 1. The overall efficiency of the turbine is 38% and average air density is 1.11 kg m 3. Determine the average electric power output in kW to three significant figures and enter the numerical value only (e.g. 0.0123, 0.123, 12.3, 123, but not 123 kW).
