Define pressure and its related SI units. Explain the relationship between pressure and force. Calculate force given pressure and area. Matter most commonly exists as a solid, liquid, or gas; these states are known as the three common phases of matter. We will look at each of these phases in detail in this section.
Key Equations. Summary. 14.1 Fluids, Density, and Pressure. A fluid is a state of matter that yields to sideways or shearing forces. Liquids and gases are both fluids. Fluid statics is the physics of stationary fluids. Density is the mass per unit volume of a substance or object, defined as ρ = m V ρ = m V. The SI unit of density is kg/m 3.

Pressure in Fluids. by Ron Kurtus (revised 28 September 2002) Pressure is a measurement of the force per unit area. Since a fluid is a liquid or a gas, its pressure applies in all directions. Fluid pressure can be in an enclosed container or due to gravity or motion.
9-1 The Buoyant Force. We should begin by defining what a fluid is. Many people think of a fluid as a liquid, but a fluid is anything that can flow. By this definition, a fluid can be a liquid or a gas. Flowing fluids can be rather complicated, so let’s start with static fluids – fluids that are at rest.
γ. g. = pressure at sections 1 and 2, = average velocity of the fluid at the sections, = the vertical distance from a datum to the sections (the potential energy), = the specific weight of the fluid ( ρ g ), and = the acceleration of gravity.
