From 1, the pressure at the wall of any vessel is perpendicular to the wall 3. because it is less dense than water, yet relatively incompressible even endstream endobj 336 0 obj <> endobj 337 0 obj <> endobj 338 0 obj <>stream Fluid Statics. endstream endobj startxref Fluid Statics means fluid at rest. 2.2).

This equation may be derived by considering the static equilibrium of a typical differential element of fluid (Fig. Pressure at any point in a fluid is the same in all directions and is transmitted through static fluids without loss (Pascal's principle) 2. For a static fluid, the only stress is the normal stress since by definition a fluid subjected to a shear stress must deform and undergo motion. Lecture notes files.
Normal stresses are referred to as pressure p. For the general case, the stress on a fluid element or at a point is a tensor For a static fluid, Fluid Statics Dam Design Dam Design Example (cont.) • hydrostatic condition: when a fluid velocity is zero, the pressure variation is due only to the weight of the fluid.

The fundamental equation of fluid statics is that relating pressure, specific mass and vertical distance in a fluid.
