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,
Aqueous thermal explosion is the result.
Decreased viscosity + increased friction = blocked fluidity,
called friction factor.
Absolute zero is the result.
