Homework Statement
Determine the speed of air at 1,2,3,4 mm from the middle of a wind turbine blade at a section 4 meters from the hub, given that the free stream velocity is 7 m/s and the turbine is moving at a speed of 18 RPM. The air temp is 27 degrees c. The length of the aerofoil is 8 meters long at a section 4 meters from the hub. Use the parabolic equation from the boundary layer theory.
