Definition

1. Noun:
   • Pascal's Law of Fluid Pressures: A fundamental principle in fluid mechanics stating that when pressure is applied to a confined, incompressible fluid, that pressure change is transmitted undiminished to every portion of the fluid and to the walls of its container. The transmitted force acts at a right angle (perpendicular) to any surface it contacts.

Usage Examples

• Noun:
  • The operation of a hydraulic lift is a direct demonstration of Pascal's law of fluid pressures.
  • Engineers rely on Pascal's law of fluid pressures when designing braking systems for vehicles.
  • A simple experiment with syringes and water can illustrate Pascal's law of fluid pressures.

Advanced Usage

• "An application of Pascal's law": A common phrase used to describe devices or systems whose function is based on this principle.
  • The hydraulic press is a classic application of Pascal's law.

Variants and Related Words

• Pascal's Law (n): The common, shortened name for Pascal's law of fluid pressures.
• Pascal's Principle (n): Another synonymous term for the same physical law.
• Hydraulics (n): The branch of science and technology concerned with the conveyance of liquid through pipes and channels, especially as a source of mechanical force, fundamentally based on Pascal's law.

Synonyms

• Pascal's Principle: An exact synonym.
• The Principle of Transmission of Fluid-Pressure: A descriptive synonym.

Related Phrases

• Confined fluid: A key condition for the law to apply; the fluid must be enclosed.
• Incompressible fluid: An ideal condition assumed by the law, meaning the fluid's volume does not change under pressure.
• Pressure transmission: The core concept described by the law.

Related Concepts

• Hydraulic Force Multiplication: A critical consequence of Pascal's law. While pressure is transmitted equally, the force exerted can be multiplied if the output surface area is larger than the input surface area (Force = Pressure × Area).
  • Using Pascal's law, a small force on a small piston can create a large force on a large piston, enabling heavy lifting.

Noun

1. pressure applied anywhere to a body of fluid causes a force to be transmitted equally in all directions; the force acts at right angles to any surface in contact with the fluid
