1 results about "Force density" patented technology

In fluid mechanics, the force density is the negative gradient of pressure. It has the physical dimensions of force per unit volume. Force density is a vector field representing the flux density of the hydrostatic force within the bulk of a fluid. Force density is represented by the symbol f , and given by the following equation, where P is the pressure: 𝐟=-∇P. The net force on a differential volume element dV of the fluid is: d𝐅=𝐟dV Force density acts in different ways which is caused by the boundary conditions.
