👉 In this context, the "assumed fluid" refers to a hypothetical substance that is believed to exist within certain systems or materials, often described as having properties similar to those of liquids but potentially exhibiting behaviors that are more fluid-like or even gas-like under specific conditions. This concept is commonly used in physics, chemistry, and materials science to describe phenomena such as supercritical fluids, which are substances above their critical temperature and pressure where they exhibit properties of both liquids and gases. These fluids can dissolve materials more effectively than gases and have unique transport properties, making them useful in various industrial applications. The exact nature of this fluid can vary widely depending on the system being studied, but it is generally assumed to have a low viscosity and high diffusivity, allowing for efficient mixing and transport of substances.
