Understanding Fluid Mechanics

Fluid mechanics is the study of fluids (liquids and gases) and the forces acting on them. It has two main branches:

  • Fluid Statics: Study of fluids at rest
  • Fluid Dynamics: Study of fluids in motion
Key Concepts
Bernoulli's Principle

In a flowing fluid, the sum of pressure, kinetic, and potential energy per unit volume remains constant.

P + ½ρv² + ρgh = constant
Continuity Equation

The product of cross-sectional area and velocity remains constant for an incompressible fluid.

A₁v₁ = A₂v₂
Tip: Visualize fluid flow by imagining water moving through pipes of different diameters.
📘 Quick Reference: Fluid Mechanics Formulas
  • Pressure: P = F / A (Pascals)
  • Hydrostatic Pressure: P = ρgh
  • Continuity Equation: A₁v₁ = A₂v₂
  • Bernoulli's Equation: P + ½ρv² + ρgh = constant
  • Reynolds Number: Re = ρvD/μ
  • Viscosity (Newton's Law): τ = μ(du/dy)
