Extracted text: C2(i)Assume that annual energy requirement of an industry is 20900 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 = 20900 kWh Propeller type wind machine is used Coefficient of performance = 0.40, Loss factor value = 0.325 Wind speed at 6 meter/sec (This wind speed should be taken from the wind data prepared for that location.) Density of air = 1 kg/m3 Capacity factor = 0.30 (1.e. 30% of the time, wind machine is producing energy at rated power) Number of hours in a month 730 hours. Annual energy density = Radius of rotor = Turbine Rating =
