Branches of Fluid Mechanics
Classification and Nature of Fluids
Factors Affecting Fluid Flow
Properties of Fluids
1

The branch of physics concerned with the study of motion, forces, and energy.

MECHANICS

1

The branch of fluid mechanics that deals with fluids at rest.

FLUID STATICS

1

A substance that deforms continuously under the application of an external shear force.

FLUID

1

The internal resistance of a fluid to flow or shear.

VISCOSITY

1

The mass per unit volume of a substance.

DENSITY

2

The branch of mechanics that deals with bodies at rest.

STATICS

2

The branch of fluid mechanics that deals with fluids in motion.

FLUID DYNAMICS

2

Fluids that have definite volume but no fixed shape.

LIQUID

2

The driving factor that causes fluids to move from regions of high pressure to low pressure.

PRESSURE GRADIENT

2

The reciprocal of density.

SPECIFIC VOLUME

3

The branch of mechanics that deals with bodies in motion.

DYNAMICS

3

The principle describing pressure in a fluid due to gravity using the equation P=ρgh

HYDROSTATIC PRESSURE

3

Fluids that have neither definite shape nor definite volume.

GASES

3

The property that determines mass per unit volume of a fluid.

DENSITY

3

The ratio of the density of a substance to the density of water at 4°C.

Specific Gravity

4

The science that studies the behavior of liquids, gases, and plasmas at rest and in motion.

FLUID MECHANICS

4

The principle stating conservation of mass in fluid flow expressed as A1v1=A2v2.

CONTINUITY EQUATION

4

The type of fluid that is highly compressible.

GAS

4

The force acting on the surface of a liquid causing it to behave like a stretched elastic sheet.

SURFACE TENSION

4

The attractive force between unlike molecules.  

Adhesion

5

The branch of science concerned with the response of fluids to forces exerted upon them.

FLUID MECHANICS

5

The principle stating that an increase in fluid velocity results in a decrease in pressure.

BENOULLI'S PRINCIPLE

5

The type of fluid that is virtually incompressible.

LIQUID

5

The characteristic of container walls that influences boundary layer development and friction.

SURFACE ROUGHNESS
5

The upward force exerted on an object submerged in a fluid.
