Fluid Dymnamics and Drag Forces
Not what you're looking for?
We would like to know the nature of the drag forces experienced by a sphere as it passes through a fluid. The sphere has a low speed. Therefore, the drag force is highly dependent on the viscosity of the fluid. The fluid density is to be neglected.
a) Use dimensional analysis to develop a model for drag force: F (MLT^-2) as a function of the radius r (L) and velocity v (LT^-1) of the sphere and the viscosity: µ (ML^-1T^-1) of the fluid.
b) What is required to use the model for F above to be of use for predictions?
