Force density - Citizendia

In fluid mechanics, the force density has the physical dimensions of force per unit volume. Fluid mechanics is the study of how Fluids move and the Forces on them Force density is a vector field representing the flux density of the hydrostatic force within the bulk of a fluid. In Mathematics a vector field is a construction in Vector calculus which associates a vector to every point in a (locally Euclidean space. In the various subfields of Physics, there exist two common usages of the term flux, both with rigorous mathematical frameworks FLUID ( F ast L ight '''U'''ser '''I'''nterface D esigner is a graphical editor that is used to produce FLTK Source code Force density is represented by the symbol f, and given by the following equation, where P is the pressure:

$\mathbf{f} = \nabla P$ . Pressure (symbol 'p' is the force per unit Area applied to an object in a direction perpendicular to the surface

The net force on a differental volume element dV of the fluid is:

$d\mathbf{F} = \mathbf{f}dV$

Thus, the force density at a point in a fluid, divided by the density, is the acceleration of the fluid at that point. In Physics, a force is whatever can cause an object with Mass to Accelerate. The density of a material is defined as its Mass per unit Volume: \rho = \frac{m}{V} Different materials usually have different
