(2) Consider the wind turbine configuration shown
in the figure. Using the control volume shown, determine an
expression for the maximum possible power generated by the
wind turbine. If you define the efficiency of the wind turbine
as the ratio of the power generated to the kinetic energy
input by the wind, what is the maximum possible efficiency?
