Dimensional Analysis of Drag Force over a Sphere
Use dimensional analysis to investigate how the drag force, F_(D), over a sphere varies as a function of velocity, v, sphere diameter, d, and fluid viscosity, mu . Determine the following:
(a) The number of pi -groups?
(b) The pi -groups?
(c) What happens to the drag force, F_(D), if you decrease d by a factor of 2 ?
