Mechanical Properties of Fluids

Pressure is defined as force per

Pressure is defined as force per unit area (P = F/A). In fluids, pressure acts perpendicular to any surface and is a scalar quantity. It's measured in

Pressure applied to an enclosed fluid

Pressure applied to an enclosed fluid is transmitted equally in all directions throughout the fluid. At the same height in a fluid at rest, pressure i

In a fluid at rest

In a fluid at rest, pressure increases with depth according to P = Pa + ρgh, where Pa is atmospheric pressure, ρ is fluid density, g is acceleration d

In steady flow

In steady flow, fluid particles follow smooth paths called streamlines that never cross. The continuity equation (Av = constant) states that the produ

For steady

For steady, non-viscous, incompressible fluid flow, the sum of pressure energy, kinetic energy per unit volume, and potential energy per unit volume r
