Fluid Mechanics - Chapter 1

The science that deals with the behavior of fluids at rest (fluid statics) or in motion (fluid dynamics), and the interaction of fluids with solids or other fluids at the boundaries.

• Fluid Mechanics

• Fluid Dynamics

• Fluid Kinematics

• Fluid Statics

The study of the motion of fluids that can be approximated as incompressible (such as liquids, especially water, and gases at low speeds)

• Fluid Mechanics

• Gas Dynamics

• Hydrodynamics

• Aerodynamics

A subcategory of hydrodynamics, which deals with liquid flows in pipes and open channels.

• Hydrodynamics

• Hydraulics

• Hydrology

• Oceanography

Deals with the flow of fluids that undergo significant density changes, such as the flow of gases through nozzles at high speeds.

• Fluid Dynamics

• Gas Dynamics

• Hydrodynamics

• Aerodynamics

Deals with the flow of gases (especially air) over bodies such as aircraft, rockets, and automobiles at high or low speeds.

• Aerodynamics

• Gas Dynamics

• Hydraulics

• Fluid Mechanics

A substance in the liquid or gas phase.

• Steam

• Mixture

• Vapor

• Fluid

The normal stress in a fluid at rest.

• Normal Stress

• Shear Stress

• Pressure

• Strain

What is a Zero Shear Stress?

• A fluid without pressure

• A fluid without shear stress

• A fluid at motion

• A fluid at rest

Gas: The vapor phase of a substance is customarily called a gas when it is __________ the critical temperature.

Vapor: Usually implies that the current phase is not far from a state of ___________.

• below; condensation

• above; evaporation

• below; evaporation

• above; condensation

How do we classify fluid flows?
