Approximate bulk modulus (K) for other substances β-Carbon nitride: 427 ± 15 GPa [7] (predicted) Water: 2.2 GPa (0.32 Mpsi) (value increases at higher pressures) Methanol 823 MPa (at 20 °C and 1 Atm) Solid helium: 50 MPa (approximate) Air 142 kPa (adiabatic bulk modulus [or isentropic bulk modulus]) Air 101 kPa (isothermal bulk modulus ...
Commonly the void is air, but it could also be vacuum, liquid, solid, or a different gas or gaseous mixture. The bulk volume of a material —inclusive of the void space fraction — is often obtained by a simple measurement (e.g. with a calibrated measuring cup) or geometrically from known dimensions.
In materials science, bulk density, also called apparent density, is a material property defined as the mass of the many particles of the material divided by the bulk volume. Bulk volume is defined as the total volume the particles occupy, including particle's own volume, inter-particle void volume, and the particles' internal pore volume. [1]
In thermodynamics and fluid mechanics, the compressibility (also known as the coefficient of compressibility [1] or, if the temperature is held constant, the isothermal compressibility [2]) is a measure of the instantaneous relative volume change of a fluid or solid as a response to a pressure (or mean stress) change.
Though the compression/heating process of solids can be constant temperature , and constant pressure (isobaric), it can not be a constant volume (isochoric), At high P-T, the pressure for the ideal gas is calculated by the force divided by the area, while the pressure for the solid is calculated from bulk modulus (K, or B) and volume at room ...
For a substance X with a specific volume of 0.657 cm 3 /g and a substance Y with a specific volume 0.374 cm 3 /g, the density of each substance can be found by taking the inverse of the specific volume; therefore, substance X has a density of 1.522 g/cm 3 and substance Y has a density of 2.673 g/cm 3. With this information, the specific ...
The particle mass density or particle density of a material (such as particulate solid or powder) is the mass density of the particles that make up the powder. Particle density is in contrast to the bulk density, which measures the average density of a large volume of the powder in a specific medium (usually air).
where is the void ratio, is the porosity, V V is the volume of void-space (gases and liquids), V S is the volume of solids, and V T is the total (or bulk) volume. This figure is relevant in composites , in mining (particular with regard to the properties of tailings ), and in soil science .
