1. The thrust of a marine propeller Fr depends on water density p, propeller diameter D, speed of advance through the water V, acceleration due to gravity g, the angular speed of the propeller , the water pressure p., and the water viscosity . You want to find a set of dimensionless variables on which the thrust coefficient depends. In other words CT= pV² D² = ƒœn (T1, T², ...TH) (1) What is k? Explain. (b) Find the 's on the right-hand-side of equation 1 if one of them HAS to be a Froude number gD/V².
