diffusion of water across a semipermeable membrane(A) Water diffuses down its concentration gradient from side 1 to side 2 of a rigid container to dilute the impermeant substance. (B) The net flux of the water increases the hydrostatic pressure on side 2, tending to force the water back to...
In this formula, the variable PG stands for pressure gradient, PD stands for pressure difference, and D stands for distance. What is an example of a pressure gradient? The most consistent pressure gradient in Earth's atmosphere is the decrease in air pressure that occurs as altitude increases....

1.7B). Before the end of the 1970s, the continental heat low was stronger, and the ocean–continent pressure gradient which is the main driving force of the ASM, is larger. However, the weakening of the continental heat low after the end of the 1970s reflects a decrease in the thermal...
and the continental backstop (seismic velocity gradient in the lower crust) are visible. The subsurface extent of the continental backstop was also determined from the gravity data. Full size image In the next sections, we first review the geology of the (U)HP felsic rocks and their rock asso...
When pressure is applied, the electron density attempts to compensate this effect by expanding in the anti-gradient directions, i.e. towards nonbonding-edges of ionic basins. A complete set of overlays (1.1 GPa, 1.9 GPa, 4.2 GPa) is given in the Supporting Materials (pdf file) and as 3D...
[23]. To address this challenge, constructing various microstructures onto a pressure sensing layer was first thought of by researchers such as pyramids, lotus leaf, and gradient wrinkles [24,25,26]. For example, Shuai et al. fabricated a highly sensitive flexible pressure sensor based on ...
While the gradient (influence of inflation pressure on the emission factor) is low in the free-rolling condition (Figure 5a), it becomes significantly higher with increasing longitudinal force (Figure 5b,c). This is probably due to an increase in the ratio between the proportion of longitudinal...

The curved path of the air is associated with centripetal acceleration and a pressure gradient perpendicular to the streamline, with the lower pressure on the inside of the curve. The pressure gradient perpendicular to the flow also affects acceleration of air in the direction of flow, but to...
