Fluid Mechanics Essentials

Reynolds Number

• Predicts flow type: laminar or turbulent

• Measures fluid viscosity

• Calculates fluid density

• Determines fluid temperature

Fluid Mechanics

• Study of gases in motion

• Study of fluids in motion and at rest

• Study of solid mechanics

• Study of thermodynamics

Hydrostatic Pressure

• Pressure due to fluid's weight

• Pressure exerted by a gas

• Pressure caused by temperature changes

• Pressure from external forces

Laminar Flow

• Chaotic, turbulent fluid motion

• Random, erratic fluid motion

• Smooth, orderly fluid motion

• Fluid motion with varying speeds

Pascal's Law

• Pressure applied to fluid is transmitted equally

• Pressure applied to a solid is transmitted equally

• Pressure applied to gas is transmitted unequally

• Pressure applied to liquid is absorbed completely
