Question

Could someone help me with this question please as I am kinda lost as in how to do these type of questions

For a wind turbine, derive, from conservation of mass, momentum and energy, the maximum power which can be extracted as a) max 2 where p is the density of air, U is the upstream wind speed, A is the swept area of 16 the wind turbine and Cs the power coefficient. P 27 [11 marks] b) Draw a diagram showing the actual power output P of a wind turbine against wind speed U. On the P-U diagram indicate the cut-in, rated and cut-off speeds [5 marks] c) Discuss how wind characteristics affect the annual power output of a wind turbine [5 marks] d Comment on the environmental, economic and social impacts due to the use of wind turbines. [4 marks]

please explain each step
