First of all technically it is called the pitch angle of a turbine blade. By saum hadi posted on february 16 2020. The pitch angle of 50 tonne unit was around 12 degree as per my observation. Blades set at a 20 degree angle meet too much resistance which may cause the motor to burn out.

Let s look at a typical case of fan selection for a new tower design. The angle of attack in airfoil design dictates the amount of blade. Principles involved is that the work done at any radius along the blade is a function of blade width angle of attack and tangential velocity squared. Generally the pitch angle of a cooling tower turbine is very from 6 degree to 15 degree depending on the operational speed and discharge.
