Bulk modulus is the proportion of volumetric stress related to a volumetric strain of some material. It is given by the ratio of pressure applied to the corresponding relative decrease in volume of the material. B = ΔP /(ΔV/V) Where: B: Bulk modulus. The units for the bulk modulus is the pascal. If a medium is not compressible at all - incompressible - the speed of sound is infinite c ≈ ∞). The change in the relative volume of the object when a unit compressive or tensile stress acts on the surface of the object uniformly is called Bulk modulus. The relation is given below. K = Bulk Modulus of Elasticity (Pa, psi) ρ = density (kg/m 3, lb/ft 3) This equation is valid for liquids, solids and gases.
It is nothing but a numerical constant that is used to measure and describe the elastic properties of a solid or fluid when pressure is applied. Multiply the isothermal tangent bulk modulus by 1.15 (to compensate for ratio of specific heats) to determine the value of the isentropic tangent bulk modulus. Bulk Modulus formula: B = -VΔP/ΔV where: B: Bulk Modulus, in Pa V: Initial Volume, in m^3 ΔV: Volume Change, in m^3 ΔP: Pressure change, in Pa The bulk modulus describes the volume elasticity of a material. Home. The bulk modulus is considered a descriptor of elastic properties because a compressed material returns to its original volume once the pressure is released. Popular Baby Names by Surname; Unit Conversions; Biology; Geometry, Trigonometry; Physics; Chemistry; Mathmatics; Medical ; Algebra; Statistics; Nutrition of Foods, … Bulk Modulus Of Elasticity Formula. The Bulk modulus helps us understand how an object reacts when compressed from all sides equally. Fluid pressure calculator solving for bulk modulus given pressure, change in volume and initial volume The sound travels faster through media with higher elasticity and/or lower density. In this article, we will discuss bulk modulus formula. The value of the isentropic tangent bulk modulus obtained in Step 3 can be used in Equation 1 to calculate the acoustic velocity. 80 times harder to compress than water with Bulk Modulus 2.15 10 9 Pa. Example - Density of Seawater in the Mariana Trench - the deepest known point in the Earth's oceans - 10994 m . The units for the bulk modulus are Pascals (Pa) or newtons per square meter (N/m 2 ) in the metric system, or … ΔP: change of the pressure or force applied per unit area on the material.
