These surfaces are distorted by hydrostatic balance toward negative anomalies of pressure produced by the bend of the low-pressure vortex cores.
In such static solutions the hydrostatic pressure in the fluid and the elastic pressure exerted by the walls of the crack are in balance.
The use of the condition of equilibrium between the ponderomotive and hydrostatic forces is necessary to obtain the power threshold to produce self-focusing.
We initially input turbulent velocity into the magnetized plate-shaped cloud which is in hydrostatic equilibrium between thermal pressure and self-gravity.
Besides arithmetical works, he wrote a treatise consisting in a collection of problems about weighing with hydrostatic a and normal balances.
The hydrostatic approximation leads to an underestimation of both the maximum growth rate and the wavenumber at which it occurs.
A representative example is shown in figure 3(b) (hydrostatic approximation: dotted line).
In a homogeneous fluid at rest, ver tical momentum conservation requires that the fluid be in hydrostatic balance.
