When a sphere falls freely through a homogeneous fluid, it reaches a terminal velocity at which the weight of the sphere is balanced by the buoyant force and the frictional resistance of the fluid. Make a dimensional analysis of this problem and indicate how experimental data for this problem could be correlated. Neglect compressibility effects and the influence of surface roughness.

A liquid of density ? and viscosity ? is pumped at volume flow rate V· through a pump of diameter D. The blades of the pump rotate at angular velocity ? . The pump supplies a pressure rise ΔP to the liquid. Using dimensional analysis, generate a dimensionless relationship for ΔP as a function of the other parameters in the problem.

Determine the form of an equation for the distance (s) that a sphere will fall in time t, if it starts with an initial velocity and the resistance of the fluid through which it falls is taken into consideration. Resistance is dependent upon the density (ρ) and viscosity (μ) of the medium and the diameter (d) and mass (m) of the sphere. Hence in addition to g, v and t these factors are incorporated.
