9. Measurement of Pressure and Hydrostatic Forces
The chapter discusses the measurement of pressure in fluid mechanics, focusing on manometers and pressure distributions on inclined surfaces. Key applications of hydrostatics include determining forces on submerged surfaces and how these principles apply to various devices like differential manometers and U-tube manometers. Important concepts such as pressure equilibrium and the principles governing manometer operation are elaborated upon.

What we have learnt
- Manometers are simple devices used to measure pressure differences in fluid systems.
- Differential manometers measure pressure differences between two points rather than absolute pressures.
- Pressure exerted on submerged surfaces is crucial for designing structures in fluid environments.
Key Concepts
- -- Manometer
- A device that measures fluid pressure by balancing the column of liquid against the pressure being measured.
- -- Differential Manometer
- A manometer that measures the difference in pressure between two points in a fluid system.
- -- Hydrostatic Pressure
- The pressure exerted by a fluid at rest due to the force of gravity.
- -- Pascal's Law
- A principle stating that pressure applied to an enclosed fluid is transmitted undiminished in all directions within the fluid.
