Given that the power P developed by a wind turbine is a function of the diameter D and rotational speed N of the rotor, and of the density p, dynamic viscosity and velocity V of the airstream, Repeating variables are [density(p), rotational speed (N) and diameter(D)] Rotational speed unit should be (1/time) b) A 1/8 scale model of a wind turbine rotor is tested in a wind tunnel at atmospheric pressure. The full-size rotor is to turn at 42 rev/min in a wind of 10 m/s velocity. Determine the required values of N and V for the model if complete dynamic similarity is to be achieved. c) If the model rotor produces 26 kW, how much power would the full-size rotor produce?
