Hydrostatics is the branch of fluid mechanics that studies incompressible fluids at rest. It encompasses the study of the conditions under which fluids are at rest in stable equilibrium as opposed to fluid dynamics, the study of fluids in motion. Hydrostatics are categorized as a part of the fluid statics, which is the study of all fluids, incompressible or not, at rest. Hydrostatics is fundamental to hydraulics, the engineering of equipment for storing, transporting and using fluids.
Aerostatics: When the fluid is a gas. In fluid statics, there is no relative motion between adjacent fluid. layers, and thus there are no shear (tangential) stresses in the fluid. trying to deform it. The only stress we deal with in fluid statics is the normal stress, which. is the pressure, and the variation of pressure is due only to the. weight of the fluid. The topic of fluid statics has significance only in gravity fields. The design of many engineering systems such as water dams and.
