1. For a tip speed ratio of λ = 1.1, prepare a plot of the angle of attack, vor blade positions of θ :0 to 2π (use increments of π/16) Direction of rotation 300m- 90 120 180 Fig.1 Darrieus water turbine. 270 Fig. 3. Flow relative to the blade. 2. At what value(s) of θ is the angle of attack an absolute maximum ? What is αηα?
