renewable energy conversion

Question 2 (a) Assuming wind speed is 19.9 m/s at standard atmospheric pressure, and air density = 1.226 J/kg.K/m³, analyse the following: i. Total power density in wind stream ii. Total power produced by a turbine of 100m diameter with an efficiency of 42%. (b) Wind at one standard atmospheric pressure and 17°C has a speed of 12.9 m/s. A 10m diameter wind turbine is operating at 5 rpm with maximum efficiency of 49.0%. Evaluate the design parameters of the wind turbine as follows: i. The total power density in the wind stream ii. The theoretical maximum power density iii. Power output of the turbine iv. Axial thrust on the turbine structure.
