WebNov 5, 2024 · 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. The SI unit of density is kg/m 3. WebThe application of the principle of conservation of energy to frictionless laminar flow leads to a very useful relation between pressure and flow speed in a fluid. This relation is called Bernoulli’s equation, named after Daniel Bernoulli (1700–1782), who published his studies on fluid motion in his book Hydrodynamica (1738).

Webwhere Q = flow rate (volume/time); ΔP = pressure difference (mm Hg); and R = resistance to flow (mm Hg x time/volume). This equation may be applied not only to a single vessel, but can also be used to describe flow through a network of vessels (i.e., the vascular bed of an organ or the even your entire systemic circulatory system). WebIn this equation and the general flow equation, the pressure drop ratio, x, is limited to a maximum value of xT. Incorporating the expansion factor into the basic liquid flow equation yields the general compressible flow model: L v G P Q C Y (4) This proved to be an acceptable model for compressible fluid flow through valves.
