Electrical Engineering _ Energy Conversion System ,

pls solve the problem  in less than 20 min.

Assume that annual energy requirement of an industry is 20800 kWh ,we calculate that what will be the size of
wind turbine that is required to be installed to meet the energy requirement.
Following assumptions are taken into account for estimation:
Annual energy requirement = 20800 kWh
Propeller type wind machine is used
Coefficient of performance = 0.40, Loss factor value = 0.325
Wind speed at 16 mph (This wind speed should be taken from the wind data prepared for that location.
Density of air = 1 kg/m3
Capacity factor = 0.30 (i.e. 30% of the time, wind machine is producing energy at rated power)
Number of hours in a year 8500 hours.
Annual energy density =
Area swept by the rotor =
Radius of rotor=
