Compressibility is an important factor when we look at how fluids behave under pressure, especially gases.
What is Compressibility?
Compressibility is how much a fluid can change in volume when pressure changes. In simpler terms, it shows us how squishy or squashed a fluid can get.
Compressibility Values
For gases, the average compressibility factor () can go above 1 when there's a lot of pressure. For example, at normal air pressure (1 atm), the compressibility of air is about . This means air doesn't compress a lot, but it can still change a little.
Bulk Modulus
The bulk modulus tells us how much a fluid resists being squished. For water, the bulk modulus is about . This means water is not very compressible when compared to gases. It takes a lot of pressure to change its volume.
When things get really pressurized, knowing about these properties is super important. It helps us understand how fluids will act, which is key for studying how they move and behave in different situations.
