any substance that cannot maintain its own shape
A substance that flows and yields to any force tending to change its shape.
A fluid is a substance without any definite shape, including both gases and liquids. Some glass may also be considered a fluid, because after many years, some glass displays a fluid motion, slowly flowing downward.
Liquids and gasses are fluid, they can flow. Fuild is used in a more general context for things which can flow or have no fixed structure. See for example, fluid membrane.
Term used in filtration and separation to include liquids, air or gas as a general term.
Any substance which will undergo continuous deformation when subjected to shear stress. Liquids and gases are fluids.
The state of matter of liquids and gases.
a substance that is fluid at room temperature and pressure
characteristic of a fluid; capable of flowing and easily changing shape
a substance that does not permanently resist distortion
a substance that flows easily
a substance that has a low resistance to flow and the tendency to assume the shape of its container
a substance which deforms continuously, or flows, when subjected to shearing forces
A substance in its liquid state.
any liquid or gas Freezing point: the temperature at which liquids will solidify or freeze upon removal of heat (e.g., the freezing point of water is +32 degrees F. or 0 degrees C.)
The material assumes the shape of its container. It could be either a liquid or a gas.
a material that can undergo flow; usually a gas or liquid.
Any kind of liquid, usually used to describe one on the outside or inside of a person's body. Examples of body fluids are: semen, vaginal secretions, saliva, and blood.
Materials in a liquid, gas, or vapor state, as opposed to a solid.
A substance which tends to conform to the outline of its container and capable of flowing as a liquid or a gas.
a substance which deforms continuously under the action of a shear force, however small. Wellbore fluids include oil and water (with or without gas in solution) and free gas.
Any liquid, gaseous or vapor substance.
matter which flows; a gas or a liquid
Any material or substance that changes shape uniformly in response to an external force imposed upon it. The term applies to liquids, gases and finely divided solids.
Any substance, whether liquid, gas or vapor, in which the particles move freely, resulting in no permanent shape and low resistance to pressure.
Liquid or water. It is important for us to drink fluids to stay healthy.
Anything that flows, either liquid or gas. Some solids can also exhibit fluid behavior over time.
A liquid or gas that flows and assumes the shape of its container.
A substance which, when in static equilibrium, cannot sustain a shear stress; a liquid or a gas. This concept is only approximated by actual liquids and gases.
a general classification of physical state, including liquids and gases.
having the properties of a gas or liquid.
Usually a gaseous or liquid substance which is capable of flowing. Air is fluid under normal conditions.
Substance that flows and changes shape.
A fluid is defined as a substance that continually deforms (flows) under an applied shear stress regardless of the magnitude of the applied stress. It is a subset of the phases of matter and includes liquids, gases, plasmas and, to some extent, plastic solids.
