Study Notes
- Fluids are substances that can flow, including liquids and gases, and do not possess a definite shape.
- When an object is submerged in a fluid at rest, the fluid exerts a force on its surface, which is called thrust.
- The pressure exerted per unit area of a fluid's surface at rest is called pressure.
- Pressure in a fluid is the same at the same horizontal level and acts perpendicularly to the surface.
- Pressure at a point in a liquid depends on the depth below the surface, density, and acceleration due to gravity.
- According to Pascal's Law, the pressure applied to an enclosed liquid is transmitted undiminished to every portion of the liquid and the walls of the containing vessel.
- Hydraulic systems operate on Pascal's Law, with the force exerted to area ratio being constant at all cross-sections.
- The pressure in a fluid column of height h and density p is given by the relation P = Pa + hρg, where Pa is the atmospheric pressure.
- This relation is only valid for incompressible fluids.
