| Also Known As | Fluid substance, liquid or gas, Newtonian fluid, non-Newtonian fluid |
What is Fluids?
Substances that flow and take the shape of their containers, including both liquids and gases. Fluids exert pressure in all directions and transmit forces through pressure. Fluid mechanics studies the behavior of fluids at rest (statics) and in motion (dynamics).

Substances that flow and take the shape of their containers, including both liquids and gases. Fluids exert pressure in all directions and transmit forces through pressure. Fluid mechanics studies the behavior of fluids at rest (statics) and in motion (dynamics).
Understanding fluid behaviour is essential in chemical engineering (pipe flow, reactor mixing, distillation), pharmaceutical manufacturing (filling of liquid dosage forms), geology (magma flow), biology (blood circulation), and environmental science (river and ocean dynamics).
Fluid flow in pipes and reactors can generate static electricity (electrostatic ignition hazard with flammable fluids). High-pressure fluid jets can cause hydraulic injection injuries. Sudden fluid pressure surges (water hammer) can rupture pipework and are an industrial hazard.
The formula or notation for Fluids is: Fluids (liquid+gas): τ = η(dv/dy); Navier-Stokes equations
