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.

Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains.

In physics, energy is the property that must be to an object in order to perform work on – or to heat – the object, and can be converted in form, but not created or destroyed.

The SI unit of energy is the joule, which is the energy transferred to an object by the mechanical work of moving it a distance of 1 metre against a force of 1 newton.

Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.

Gauge pressure (also spelled gage pressure) is the pressure relative to the ambient pressure.

A temperature is an objective comparative measurement of hot or cold.

It is measured by a thermometer.

Several scales and units exist for measuring temperature, the most common being Celsius (denoted °C; formerly called centigrade), Fahrenheit (denoted °F), and, especially in science, Kelvin (denoted K).
