ABSTRACT
Fluid statics is that branch of mechanics of fluids that deals primarily with fluids at rest. Problems in fluid statics are much simpler than those associated with the motion of fluids, and exact analytical solutions are possible. Since individual elements of fluid do not move relative to one another, shear forces are not involved and all forces due to the pressure of the fluid are normal to the surfaces on which they act. Fluid statics may thus be extended to cover instances in which elements of the fluid do not move relative to one another even though the fluid as a whole may be moving. With no relative movement between the elements, the viscosity of the fluid is of no concern.
