Problem Statement: The power P generated by a certain windmill design depends upon its diameter D, the air density p, the wind velocity V, the rotation rate 2, and the number of blades n. Part [A] - Write this relationship in dimensionless form? Part [B] - A model windmill, of diameter 50 cm, develops 2.5 kW at sea level when V = 38 m/s and when rotating at 4600 rev/min. What power will be developed by a geometrically similar prototype (n is the same for both mills), of diameter 5 m, in winds of 10 m/s at 1800 m standard altitude?
