2. by considering a constant pore water pressure coefficient (u= r u . .z, where is the total unit weight of the soil and z is the depth of the point below the soil surface). Using the piezo surface or r u , the value of pore water pressure at any point is determined. Integratio...
What is the pressure at the bottom of a river (12 m deep) if the air pressure over the river is 98.23 kPa? The density of the river water is 988 kg/m3. What is the density of water at a depth where pressure is 70.0 atm, g...

The bottom-hole pressure can be obtained from the following equation while assuming a zero pressure at the exit of the mud return pipeline.(1)Pbh=ρmght+Pawhere Pbh is bottom-hole pressure, ρm is mud density, g is gravitational acceleration, ht is total well depth, Pa is annular ...
The pressure waves generated by the photoacoustic effect induced by the micro-bead thermal expansion obeys the acoustic wave equation: $$\frac{1}{\rho {c}_{s}^{2}}\frac{{\partial }^{2}{p}_{t}}{\partial {t}^{2}}-\nabla \frac{1}{\rho }\left(\nabla {p}_{t}\right)=0,$...
Soil water retention is usually described by the water content at field capacity (FC; pressure head −33kPa), permanent wilting point (pressure head −1500kPa) with their difference referred to as available water content (AWC) for plants. ...
At this time, the abscission space exhibits high resistance while the surrounding rock displays relatively low resistance. After a period, under the influence of mining action and roof rock pressure, the overlying rock is deformed and broken, and consequentially a large number of cracks are formed...
