Hydrostatics deals with the study of fluids at rest or moving with uniform velocity as a solid body, so that there is no relative motion between fluid elements (or layers). There is no shear stress in a fluid at rest. Hence, only normal pressure forces are present in hydrostatics. Engineering applications of hydrostatics principles include the study of forces acting on submerged bodies such as dam faces, gates & others and the analysis of stability of floating bodies. The particles of fluid are at rest, there is no tangential or shear stress between the fluid particles. In hydrostatics, all forces act normally to the boundary surface and are independent of viscosity.
The laminar flow generally occurs : In the fluid flowing with low velocity and in the fluid layer moves in straight line. The value of Reynolds number (Re) is less than 2000. Shear stress in laminar flow depends only on the viscosity... more
The laminar flow generally occurs : In the fluid flowing with low velocity and in the fluid layer moves in straight line. The value of Reynolds number (Re) is less than 2000. Shear stress in laminar flow depends only on the viscosity of the fluid and independent of the density. Examples: Ground water flow, Rise of water in plants through their roots etc
