Bulk Modulus (Noun)
Meaning
The ratio of the change in pressure acting on a volume to the fractional change in volume.
Classification
Nouns denoting quantities and units of measure.
Examples
- The bulk modulus of a material is a measure of its resistance to uniform compression, defined as the ratio of the change in pressure to the fractional change in volume.
- The bulk modulus of water is approximately 2.15 GPa, indicating that it is relatively incompressible.
- To calculate the bulk modulus, we need to know the change in pressure and the resulting change in volume of the material.
- The bulk modulus of a gas is typically much lower than that of a solid or liquid, due to its greater compressibility.
- Engineers use the bulk modulus to design systems that involve the compression of fluids, such as hydraulic systems and pumps.
