Nam QI: 1. Suppose that the power to drive a propeller of an airplane depends ond (diameter of the propeller), U (free-stream velocity), 6 (angular velocity of propeller), c (velocity of sound), p (density of fluid), and (viscosity). Find the dimensionless groups. In your opinion, which of these are the most important and should be duplicated in a model testing? (Take p U d as repeating variables). a I the
