What is an example of bulk modulus?
The value of bulk modulus equals the pressure change x 100 required to cause a one percent change in volume. EXAMPLE: MIL-H-83282 oil has a bulk modulus of 3.0 x 105 psi. Thus, a pressure increase of 3000 psi will reduce its volume by 1.0%.
What is bulk modulus in physics?
bulk modulus, numerical constant that describes the elastic properties of a solid or fluid when it is under pressure on all surfaces. The applied pressure reduces the volume of a material, which returns to its original volume when the pressure is removed.
How do you calculate bulk modulus of elasticity?
Mathematically, bulk modulus of elasticity is expressed as given under. Bulk modulus of elasticity K=PVolumetric strain=P−ΔVV where P denotes the pressure applied to the body, ΔV denotes the change in the volume of the body due to the applied stress (or pressure) and V denotes the original volume of the body.
What are the applications of bulk modulus?
It can be used to predict compression, calculate density, and indirectly indicate the types of chemical bonding within a substance. The bulk modulus is considered a descriptor of elastic properties because a compressed material returns to its original volume once the pressure is released.
Which one the following is bulk modulus K of a fluid?
Explanation: Bulk Modulus k is related to the compression of a liquid and the decrease in volume per unit volume. It is the ratio of compressive stress to the volumetric strain. Explanation: k = 1/β, where k= Bulk Modulus of elasticity and β= compressibility.
What is bulk modulus formula Class 11?
Bulk modulus is the ratio of hydraulic stress to the corresponding hydraulic strain. Denoted by ‘B’ B = -p/(ΔV/V)
What is called bulk modulus?
The bulk modulus ( or. ) of a substance is a measure of how resistant to compression that substance is. It is defined as the ratio of the infinitesimal pressure increase to the resulting relative decrease of the volume.
What is the bulk modulus elasticity?
The Bulk Modulus Elasticity – or Volume Modulus – is a material property characterizing the compressibility of a fluid – how easy a unit volume of a fluid can be changed when changing the pressure working upon it. The Bulk Modulus Elasticity can be calculated as. K = – dp / (dV / V0)
Which has high bulk modulus?
Below are the three moduli values for selected materials. The bulk modulus of diamond is the highest as it is the hardest known material….Measurement of bulk modulus.
| Material | Diamond |
|---|---|
| Young’s modulus (GPa) | 1120 |
| Bulk modulus (GPa) | 540 |
| Shear modulus (GPa) | 450 |
What is reciprocal of bulk modulus?
The ratio of the change in pressure to the fractional volume compression is called the bulk modulus of the material. The reciprocal of the bulk modulus is called the compressibility of the substance.
