The drag equation is essentially a statement that the drag force on any object is proportional to the density of the fluid and proportional to the square of the relative flow speed between the object and the fluid. The factor of comes from the dynamic pressure of the fluid, which is equal to the kinetic energy density. http://brennen.caltech.edu/fluidbook/basicfluiddynamics/potentialflow/complexvariables/flatplate.pdf
