Pressure prediction: analysis of mud weights
To control a well, operators generally use a mud weight that will exert a pressure close to the expected pore pressure. When drilling mud kicks or blows out, the pressure from the mud is less than, but usually close to, pore pressure. Calculating pressure from mud weight. When the drilling mud kicks or blows out, pore pressure can be calculated ...

Ultimate Guide To Ore Washing
Add a high-pressure water flushing device on the fixed screening machine. The flushing water pressure is generally 0.2-0.3 MPa, and the water consumption per ton of ore is 1 ~ 2 m3. When the raw ore contains little mud and the cohesiveness is not strong, the use of such combination can meet the requirements of washing.

Solved If a plant cell with a solute potential of -0.2 MPa
If a plant cell with a solute potential of -0.2 MPa is placed in a beaker of pure water, at equilibrium it will have a pressure potential of +0.2 MPa because the cell wall prevents cell expansion. If that cell is then placed in a solution with a solute potential of -0.3 MPa that is open to the atmosphere (draw a picture if it helps you),
