Continuity, energy and momentum equations applied to control-volume analysis. An aquarium tank has a m m 3 m 1.5 m window AB for viewing the inhabitants. In fluid statics, there is no relative motion between adjacent fluid layers. The pressure due to the fluid always acts perpendicular the surface.A particle underwater will feel the same pressure from all directions.Pressure increases linearly with depth. P = g h assumes a constant density and thus is valid only for incompressible fluids like water or oil, but not for compressible fluids like air.More items Okay, but P 2 A 1 Im sorry, yes, now, lets write P 2 is the same as P 1. Two points at the same depth in a static fluid have the same pressure.

Substituting these geometric relations and dividing Eq. p z - p s = (z/2) (g + a z ) By shrinking the fluid element to a point, i.e., x, y, and z approach zero, it can be seen that. Fluid mechanics is the branch of physics that studies fluids and forces on them. In this context, the term "fluid" refers to either liquid or gases.It is a macroscopic, statistical approach to analyzing these interactions at a large scale, viewing the fluids as a continuum of matter and generally ignoring the fact that the liquid From Newtons second law, a force balance in the x- and z- directions gives (33a) (33b) where ris the density and W mg rg x z/2 is the weight of the fluid element. Fluid Statics deals with fluids at rest while Fluid Dynamics studies fluids in motion.
