Gradient

The slope,or change in elevation,of land or improvements such as a pipe or a road.It is expressed as the ratio of inches (or feet) of rise or fall over a specified distance. It is similar to the concept of pitch in roofing.Figure A (above) has a gradient of 1:12 because the grade increases by 1 foot over a distance of 12 feet. Figure B has a gradient of 1:6.

However, the pressure gradient for a Newtonian fluid is sharper than for a non-Newtonian fluid.
At the beginning of the dyeing process, the concentration and pressure gradient of the sample were high, as was the rate of diffusion--this allowed dye to permeate and diffuse into the log quite rapidly.
Where G = [partial derivative]p / [partial derivative]x is a constant pressure gradient, in the x direction, v is coefficient of viscosity of the fluid, k is permeability of the porous medium.

Very little is known about the radial pressure gradient [9].
The pressure gradient is therefore reduced, and the brain and dura tamponade against the fistulous connection, trapping the air intracranially.
Apparently, other high-temperature mechanisms for removing water, such as an increased hydraulic pressure gradient, are at work in the sheets of higher basis weight.
The potential of a tornado to wreak destruction is locked into elements of (1) its wind speed, (2) the strength of its pressure gradient, and (3) its ancillary airborne debris.
Recent clinical studies suggest that the resulting pressure gradient changes preferentially shunt particles into the tumor compartment, increasing uptake by the tumor but not by normal liver tissue.
