PASCAL'S LAW, ARCHIMED'S PRINCIPLE AND BERNOULLI'S PRINCIPLE
▎Pascal's Law
Definition: When pressure is applied to a confined fluid, the pressure change is transmitted undiminished throughout the fluid in all directions.
Key Points:
• Hydraulic Systems: Enables devices like hydraulic lifts and brakes to amplify force.
• Force Multiplication: A small force applied over a small area can create a larger force over a larger area.
• Mathematical Expression: P = F/A
Applications: Hydraulic machinery, automotive braking systems, and various industrial applications.
---
▎Archimedes' Principle
Definition: An object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid it displaces.
Key Points:
• Buoyancy: Explains why some objects float while others sink.
• Direction of Force: The buoyant force opposes gravity.
• Mathematical Expression: Fᵦ = ρ ⋅ V ⋅ g
Applications: Ship design, hot air balloons, and understanding the behavior of objects in fluids.
---
▎Bernoulli's Principle
Definition: In a flowing fluid, an increase in velocity occurs simultaneously with a decrease in pressure or potential energy.
Key Points:
• Fluid Dynamics: Explains lift generation for airplane wings and the operation of carburetors.
• Pressure-Velocity Trade-off: Highlights the relationship between fluid speed and pressure.
• Mathematical Expression: P + ½ ρ v² + ρ gh = constant
Applications: Aerodynamics, fluid flow in pipes, and various engineering designs involving fluid movement.

▎Summary
• Pascal's Law focuses on pressure transmission in fluids, enabling hydraulic systems.
• Archimedes' Principle addresses buoyancy and the behavior of objects in fluids.
• Bernoulli's Principle relates to the behavior of moving fluids and the interplay between pressure and velocity.
These principles are foundational in fluid mechanics and have numerous applications in engineering and physics.
