Fluid  statics  is that branch  of mechanics  of fluids that deals primarily  with  fluids at rest.  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. With no relative movement between the elements, the viscosity of the fluid is of no concern.  At first it will be examined  the variation of pressure throughout an expanse of fluid.Then  it will be studied the forces caused by pressure  on solid surfaces in contact  with  the fluid, and  also the effects  (such  as buoyancy)  of these  forces in certain circumstances.

• Distribution of Pressure in the Fluid

• Hydrostatic Pressure
