Dimensional analysis-examples homework 1. the drag force fd (or lift force f) on a submerged object (such as submarine) is a function of the fluid density p, the flow velocity v, the characteristic dimension of the object d, and the fluid viscosity u. fd=/(p, v, d, u).express the drag and lift force in non-dimensional form.
