Study Notes
Dilatação Volumétrica Aparente (Apparent Volumetric Expansion)
Definition:
- Apparent volumetric expansion is the increase in volume of a liquid when its temperature increases, without considering the expansion of the container.
Key Concepts:
- Real expansion: The actual increase in volume of the liquid due to temperature change.
- Apparent expansion: The observed increase in volume, which includes the expansion of the container.
Calculations:
- Apparent volumetric expansion coefficient (β_app): β_app = (ΔV_app / V_i) / ΔT where ΔV_app is the apparent volume change, V_i is the initial volume, and ΔT is the temperature change.
Importance:
- Apparent volumetric expansion is essential in engineering and scientific applications, such as:
- Designing containers and pipes for liquids
- Calculating heat transfer and energy requirements
- Understanding phenomena like thermal expansion and contraction
Factors Affecting Apparent Expansion:
- Thermal expansion of the container: The container's material and its thermal expansion coefficient affect the apparent volumetric expansion.
- Initial volume and temperature: The initial conditions of the liquid influence the apparent expansion.
- Temperature change: The magnitude of the temperature change impacts the apparent volumetric expansion.
