Fluids

The behavior of fluid flow is influenced by several factors, including viscosity, cohesion, adhesion, and external forces. Viscosity determines how thick or thin a fluid is, with thicker fluids exhibiting slower flow rates due to increased internal friction.

Fluids

Topic flotante

water flows faster at the centre of a stream or river than along the edges.

The fluid’s attraction to the material the pipes and tubes are made of slows down the flow of the fluid.

Attraction between the particles of one and another substance.

Adhension

attraction among the particles that form the surface of a liquid

Liquids surface

Surface Tension

Less viscous fluids are thin and runny and have faster flow rates.

Thicker fluids are more viscous and have slower fl ow rates.

How strongly particles of a fluid attract

Cohension

How easily fluid’s particles past each other

Viscosity

• the type of fl uid that is flowing (thin fluids flow faster than thick ones) • the force pushing on the fluid (stronger forces produce faster flow rates) • the size of the pipe or opening the fluid is flowing through (larger openings allow for faster flow) • the type of surface over which the fluid is flowing (smooth surfaces allow for faster flow)

Volume of the fluid moving in a certain time.
