Noun
pressure gradient (plural pressure gradients)
The rate of decrease (gradient) of pressure in space at a fixed time. The term is sometimes used to denote simply the magnitude of the gradient of the pressure field.
A pressure gradient is applied; as a result, water moves across the very permeable membrane rapidly, "dragging" along with it many dissolved substances, including ones with large molecular weights, which are not cleared as well by hemodialysis. Source: Internet
At zero to one-third bar suction, water is pushed through soil from the point of its application under the force of gravity and the pressure gradient created by the pressure of the water; this is called saturated flow. Source: Internet
Because the Rossby number is low, the force balance is largely between the pressure gradient force acting towards the low-pressure area and the Coriolis force acting away from the center of the low pressure. Source: Internet
Cause Oxygen passively diffuses in the lung alveoli according to a pressure gradient. Source: Internet
Since the pressure gradient normal to the flow within a boundary layer is approximately zero for low to moderate hypersonic Mach numbers, the increase of temperature through the boundary layer coincides with a decrease in density. Source: Internet
However, due to the lack of proteins, no substantial pressure gradient can be established to draw fluids from the tissue back into the blood stream. Source: Internet
