what is density of fluids
Answers
Answer:
The SI unit of density is kg/m3. kg/m 3 . ... Pressure due to the weight of a liquid of constant density is given by p=ρgh p = ρ g h , where p is the pressure, h is the depth of the liquid, ρ is the density of the liquid, and g is the acceleration due to gravity.
Answer:
Variable density fluids are those that having a density that varies as a function of pressure into the subterranean formation. Such a fluid comprises a base fluid and a portion of elastic particles
Fluids are often regarded as continua in most treatments of heat and mass transfer in engineering. This treatment makes it possible to introduce the concept of fluid (liquid or gas) density at a point. On this basis, the mass density of a liquid, ρ, is simply the mass of a liquid contained in a macroscopic .
volume, whereas the amount-of-substance density represents the amount (number of moles) of a liquid contained in the same volume. The density of a liquid is a relatively strong function of temperature at constant pressure, but a relatively weak function of pressure at constant temperature. This is because, in the liquid phase, the molecules that comprise the liquid move around largely in the well region of the Van der Waals Forces between them.
Thus, increases in molecular energy cause an expansion as the molecules stray further out into the relatively-weak attractive region of the potential. However, as the pressure is increased, the tendency for the molecules to be pushed further together is opposed by the strong repulsive forces between molecules.
