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 ...

While liquids and solids are similar in terms of density there are also ... be no such thing as a supercritical fluid after all. Even at arbitrarily high pressure, there will always be some ...

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.
