Buckingham Pi Theorem Class Problem #3 A model propeller is being tested to determine thrust characteristics. The variables that are deemed important to the analysis are thrust, T, density, ρ, rotational speed ω, speed of advance, V, propeller diameter, d, shaft depth ,h and viscosity, H. Find the non-dimensionless groups that define this experiment. Hint: Dimensions of thrust are ML/T2
