Fluids are materials that have no fixed shape and are free to flow, such as gases. Gases are also fluids.Here are some examples of fluids:WaterBloodAirGasHydrogenHeliumOxygen etc...
because the material may be safe lubricate and may not require cutting fluid .
water/gasses
Permeability is a measure of how easily fluids can flow through a porous material such as soil or rock. It is a property that affects the movement of fluids like water and gases through the material. Materials with high permeability allow fluids to flow through them easily, while materials with low permeability restrict fluid flow.
Some examples of incompressible fluids include water, oil, and gasoline. These fluids do not change their volume significantly when subjected to pressure.
Two types of materials that are considered to be fluids are liquids and gases. Liquids have a definite volume but take the shape of the container they are in, while gases have neither a definite volume nor shape and expand to fill their container.
depends what fluids, but all industries use some sort of fluids in most proccesses

True
Indelible fluids are inks or dyes that cannot easily be removed or erased once they have been applied. They are typically used for marking materials or documents to prevent alteration or tampering.
Some examples of smart materials include shape memory alloys (e.g. Nitinol), piezoelectric materials, self-healing polymers, and magneto-rheological fluids. These materials can react to external stimuli such as temperature, pressure, or magnetic fields to exhibit unique properties like changing shape, generating electricity, repairing damage, or altering viscosity.
