3-11 Principles of Fluid Dynamics

Principles of Fluid Dynamics


Viscosity = density of the fluid.


Liquid takes the shape of the container

that it fills but retains a fixed volume

and an incoming solid with defined shape and volume must have

constant viscosity to increase velocity and decrease abrasion.


Temperature must be neither too hot nor too cold

to prevent pressure differences and surface stresses.


The fluid flow and penetrating shape must be

relatively steady with time (hydrostatic equilibrium),



Titillating touch + increased time = overflowing viscosity,

called Erosdynamic.


Aqueous thermal explosion is the result.


Decreased viscosity + increased friction = blocked fluidity,

called friction factor.


Absolute zero is the result.
