The bulk modulus is a property of materials in any phase but it is more common to discuss the bulk modulus for solids than other materials. Gases have a bulk modulus that varies with initial pressure, which makes it more of a subject for thermodynamics — in particular the gas laws. The reciprocal of bulk modulus is called compressibility. Its symbol is usually β (beta) but some people prefer κ (kappa).

Considering first the modulus dependence, it is apparent that if for the sponges of a given Aw we consider E. and P. to be invariant over the range of bulk density (a reasonable assumption considering the similarity of the formulations) then equation (3) reduces to equation (1) with = C1E.

Nov 14, 2011· Bulk modulus gives an idea of change in volume of a solid substance as the pressure on it is changed. As for the solid, bulk modulus is a property of fluids too, it indicates the compressibility of a fluid. Fairly compressible fluids have a low bulk modulus and slightly compressible fluids have a high bulk modulus.

ΔK d is an increment of bulk modulus caused by fluid saturation. These equations indicate that fluid in pores will affect bulk modulus but not shear modulus, consistent with the earlier discussion. As pointed out by Berryman, a shear modulus independent of fluid saturation is a direct result of the assumptions used to derive Gassmann''s equation.

The bulk modulus, K, adapted from Nye (1957) for a material with fiber symmetry (Cusack and Miller, 1979), is given by: (9) K = - 2 c 13 2 + ( c 11 + c 12 ) c 33 c 11 + c 12 - 4 c 13 + 2 c 33 For all calculations, we also assume an isotropic index of refraction.

Bulk modulus is the measure of the decrease in volume with an increase in pressure. The "modulus of elasticity" of a liquid varies widely, depending on the specific gravity and temperature of the liquid. Typical values are less than 30,000 psi to greater than 300,000 psi, ...

Nov 02, 2015· The main difference between modulus of elasticity and modulus of rigidity is that the modulus of elasticity describes how a material gets deformed when a force is applied at right angles to a surface of an object, causing the material to elongate or shorten while the modulus of rigidity describes how a material gets deformed when a force is ...

The primary particles have a smooth, non-micro- porous surface of about 5 to 30 nm. In the flame, the primary particles fuse into larger units, called aggregates, with sizes from about 150 to 500 nm. As the aggregates cool, they form flaky tertiary structures of about 1 to 250 µm in size, called agglomerates.

Example – 3: A volume of 5 litres of water is compressed by a pressure of 20 atmospheres. If the bulk modulus of water is 20 × 10 8 N/m²., find the change produced in the volume of water. Density of Mercury = 13,600 kg/m³; g = 9.8 m/s².

A modulus is the remainder after a number has been divided into another. 3 divides into 10 with a remainder of 1. So 1 is the modulus of 10 divided by 3.

Rhenium is a chemical element with the symbol Re and atomic number 75. It is a silvery-gray, heavy, third-row transition metal in group 7 of the periodic table. With an estimated average concentration of 1 part per billion, rhenium is one of the rarest elements in the Earth''s crust. Rhenium has the third-highest melting point and highest boiling point of any stable element at 5903 K. Rhenium resembles .

After the bulk moduli of the pore-fluid components are determined, the effective bulk modulus of the total fluid is determined using Wood''s equation. Biot''s Coefficient In Fig. 2.A.2, the bulk modulus of the total rock K (effective rock bulk modulus) was shown to be dependent on three bulk moduli: the pore-fluid bulk modulus, Kfl; the matrix bulk modulus, Kma; and, the dry-rock bulk modulus, Kdry.

The Bulk modulus of a substance describes its resistance to uniform compression. It is the ratio of infinite increase in pressure to the resulting decrease in the volume. The SI unit of bulk modulus is pascal and dimensional form is M 1 L-1 T-2.

material (bulk property) of which the cell edges and faces are made of, and ρ¯ is the foam density normalised with the bulk density of the material, the latter taken as 1200 kg/m3.

Bulk Modulus of a Gas. Unlike a liquid, a gas is considered compressible, since a relatively low pressure change will noticeably change the volume that a gas occupies. Due to this fact the bulk modulus will change directly with pressure. The bulk modulus can be found by taking the derivative $frac{dp}{dρ}$.
