A solid sphere of diameter d and density ph falls in a fluid of density p and kinematic viscosity u.The gravitational acceleration is g and the terminal velocity is y (a) Determine the non-dimensionalt o for dependence of the viscosity on the other parameters. (b) If a model sphere with di-d/z is use test, determine the kinematic viscosity of the fluid and the terminal velocity vi that make the problem similar. (25 points) perform a model
