Topics in Fluid Pressure

1

1. Fluid, Thrust, and Pressure

  • A fluid has no definite shape of its own and takes the shape of its container.
  • Fluids include both liquids and gases.
  • Solids resist shearing stress strongly, but fluids offer very little resistance to shearing stress.
2

2. Pressure Due to a Liquid Column

  • The pressure exerted by a liquid column depends on depth and density only.
  • It does not depend on the shape of the container or the amount of liquid in it.
  • Pressure at the same depth in the same liquid is the same at all points.
3

3. Pascal’s Law and Hydraulic Devices

  • Pascal’s law states that pressure in a fluid in equilibrium is the same everywhere if the effect of gravity can be neglected.
  • If pressure is increased in one part of an enclosed liquid, it is transmitted equally to all parts of the liquid.
  • A small force on a small piston can produce a large force on a larger piston.

4. Effect of Gravity, Atmospheric Pressure, and Hydrostatic Paradox

  • Gravity makes pressure increase with depth in a liquid.
  • Liquid pressure is the same at all points at the same depth.
  • The liquid pressure at depth h is greater than atmospheric pressure by ρgh.
