This question is worth 12 marks. a. The wind farm could be located on the large flat-topped hill to the east of the community (Site WT1), or on open land to the south of the community (Site WT2). The wind speed distribution at Site WT1 can be described by the Weibull distribution, where k = 4.2 and A = 12.2. The wind speed distribution at Site WT2 can also be described by the Weibull distribution, where k = 2.5 and A = 9.6. Estimate the median wind velocity at Sites WT1 and WT2. Provide screenshots of how you achieved your answers. (4 marks) b. When the site is chosen, it is proposed that three-blade type wind turbines are installed. The turbine blades are 80.0 m in length, the power coefficient is 0.550, and the average air density is 1.21 kg m-3. Site WT1 can accommodate three wind turbines, whereas Site WT2 can accommodate seven wind turbines. It is estimated that the turbines can operate for 85.0% of the time at Site WT1, and 93.0% of the time at Site WT2. Based upon your answers to Part (a) of this question, estimate the maximum energy that could be extracted annually from the wind at Sites WT1 and WT2. Assume one year is approximately 3.1536 x 107 s.
