Bulk Modulus of Elasticity Formula:
| From: | To: |
The Bulk Modulus of Elasticity is a material property characterizing the compressibility of a fluid. It represents the ratio of the infinitesimal pressure increase to the resulting relative decrease of the volume.
The calculator uses the Bulk Modulus of Elasticity formula:
Where:
Explanation: The formula calculates the bulk modulus by dividing the change in pressure by the volumetric strain (change in volume divided by original volume).
Details: The bulk modulus is crucial for understanding fluid compressibility, which is important in hydraulic systems, material science, and various engineering applications where fluid behavior under pressure needs to be analyzed.
Tips: Enter change in pressure in Pascal, change in volume in cubic meters, and fluid volume in cubic meters. All values must be positive and greater than zero.
Q1: What does a high bulk modulus indicate?
A: A high bulk modulus indicates that the fluid is relatively incompressible and requires significant pressure to achieve a small volume change.
Q2: How does temperature affect bulk modulus?
A: Generally, bulk modulus decreases with increasing temperature as most fluids become more compressible at higher temperatures.
Q3: What are typical bulk modulus values for common fluids?
A: Water has a bulk modulus of approximately 2.15 GPa, while oils typically range from 1.0-1.8 GPa at room temperature.
Q4: Why is bulk modulus important in hydraulic systems?
A: In hydraulic systems, bulk modulus affects system stiffness, response time, and can cause pressure surges or water hammer effects.
Q5: How is bulk modulus related to sound speed in fluids?
A: The speed of sound in a fluid is proportional to the square root of the bulk modulus divided by the density of the fluid.
