Document Summary
Fluid statics is the study of fluids when there is no motion between particles. This is only the case when there is zero shear stress. In fluid statics problems, since there is 0 shear stress, we focus on the only remaining force effect. There are three main scenarios of a fluid statics problem: We will consider them all in this course. Pressure at a point in a static fluid. The pressure at any given point is the same in all direction in either a static fluid (any of the three types). From pascal"s law, we are able to derive two important conclusions: The pressure force is always going to be acting perpendicular to the surface that it is in contact with. The pressure force is always directed towards the surface. An equation representing pressure variation in a fluid can be defined in terms of each direction as.
