This chapter covers the analysis of pressure fields in fluids at rest, examining the relationship between pressure, body forces like gravity, and the effects of hydrostatic equilibrium. It discusses the distinctions between gauge pressure and absolute pressure while introducing concepts such as hydrostatic pressure distribution and capillarity effects. The foundations laid here are crucial for understanding fluid behavior in both static and dynamic conditions.

This chapter covers the analysis of pressure fields in fluids at rest, examining the relationship between pressure, body forces like gravity, and the effects of hydrostatic equilibrium. It discusses the distinctions between gauge pressure and absolute pressure while introducing concepts such as hydrostatic pressure distribution and capillarity effects. The foundations laid here are crucial for understanding fluid behavior in both static and dynamic conditions.
Pressure in fluids acts normal to the surface in a fluid at rest.
Hydrostatic pressure changes linearly with depth in a fluid column.
Capillary action results from the balance between surface tension and weight of the fluid.
A spatial distribution of pressure values within a fluid determined by various forces acting on the fluid.
The pressure exerted by a fluid due to its weight when the fluid is at rest, varying linearly with depth.
Pressure measured relative to local atmospheric pressure; positive when above atmospheric pressure and negative (vacuum) when below.
The ability of a liquid to flow in narrow spaces without external forces, influenced by surface tension and adhesion to surfaces.
A specified region within space through which fluid flows for analyzing fluid motion, forces, and pressure distributions.
