• ### Wind Turbine Efficiency

The turbine is most efficient when the downstream velocity is one third of the upstream. This means the most power can be extracted from the wind in this configuration. Here is a graph of the efficiency curve (the x-axis shows the ratio of velocities, the y-axis shows the efficiency): You can see from the graph when Z=1, the fluid passes
