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: . WebSep 12, 2024 · As for the magnitude of the field, that is indicated by the field line density —that is, the number of field lines per unit area passing through a small cross-sectional area perpendicular to the electric field. This field line density is drawn to be proportional to the magnitude of the field at that cross-section.

WebDrag force F D is found to be proportional to the square of the speed of the object. Mathematically F D ∝ v 2 5.14 F D = 1 2 Cρ Av 2, 5.15 where C is the drag coefficient, A is the area of the object facing the fluid, and ρ is the density of the fluid. Athletes as well as car designers seek to reduce the drag force to lower their race times. WebTo make this concept precise, we use the idea of pressure. Pressure is defined to be the amount of force exerted per area. {\Large P=\dfrac {F} {A}} P = AF. So to create a large amount of pressure, you can either exert a large force or exert a force over a small area (or do both).

A body force is simply a type of force, and so it has the same dimensions as force, [M][L][T] . However, it is often convenient to talk about a body force in terms of either the force per unit volume or the force per unit mass. If the force per unit volume is of interest, it is referred to as the force density throughout the system. A body force is distinct from a contact force in that the force does not require contact for transm… WebFor a single species of particle, the force density is the force on a single dipole multiplied by the number of dipoles per unit volume Np. By definition, the polarization density P = Np p , so it follows that the force density due to polarization is This is often called the Kelvin polarization force density .
