Speed of wind turbine to the speed of air

AI Thread Summary
The relationship between incoming air velocity and wind turbine RPM is complex and influenced by blade design and wind speed. To design an effective turbine, one should start with the expected mean wind speed and desired rotation speed, then focus on blade design. Key factors include the size of the turbine and the lift-to-drag ratio of the blades. There isn't a straightforward formula; understanding the aerodynamics of turbine blades is crucial. Proper design will ensure optimal performance based on these parameters.

hi!...
Does anyone know the relationship (i mean formulas) relating to the incoming air velocity to the rpm of a wind turbine?..i need to have a design in the generator part and also the parameters of the propeller..thanks!

best regards, :)

The speed of the turbine would depend on the blade design and the wind speed, you are looking at this the wrong way round, start with the mean wind speed you expect, decide what speed you want the turbine to rotate at and then design your blades.
 
It's related to the size of the turbine and the lift to drag ratio of the blades. There isn't a simple relationship - you have to know how big the turbine is and what the characteristics of the airfoil are. The best place to start is the aerodynamics of the turbine blades.
 
thanks for the reply :)..do you have an idea on the blade design?..or just a simple design?..
 
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
Thread 'Beam on an inclined plane'
Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
