Reading Assignment: Please study the following chapter in order to solve this HW assignment: "Chapter 8 on Wind Power Technology" from Renewable Energy Resources by Twidell and Weir, 3rd edition, 2015. Question 1 (10+10+10+10=40) The calculation of power coefficient Cp by linear momentum theory can proceed in terms of b=uzlu, instead of in terms of a = 4,-4. Show that: u (1-b?)(1+b) (a), 2 (b) C, is maximum at 16/27 when b=1/3 1-b (c) a = 2 (d) Thrust Coefficient= Cr=(1-b?)
