If the fluid density of the mixture measured with a differential-pressure tool is affected by friction, the computed holdup will be too large. The estimated slip velocity and calculated water flow ...

After accepting a friction affected differential-pressure density log from a service company, one has to decide on a correction method for obtaining the true density of the downhole fluid mixture.

The pressure therefore obeys an equation of state, which involves only bulk properties of the fluid (temperature T, number density ρ, and so on). Hydrodynamics provides a third definition of P ...

it is simply a convenient name for the quantity (half the density times the velocity squared), which represents the decrease in the pressure due to the velocity of the fluid. We can also express the ...

The high-density water causes greater pressure within ... (Elastic response is a term that describes how fluid pressure physically pushes and pulls the rock.) They found that adding the rock ...

The movement and space between particles in a fluid affects the amount of pressure the fluid exerts. This means that the pressure in a fluid changes depending on its height, depth and temperature.
