Fluid mechanics organigram

The study of fluids encompasses their movement, properties, and behavior under various conditions. Fluids, such as liquids and gases, exhibit different flow patterns, which can be either smooth (

Fluid mechanics organigram

fluids

fluids under pressure

laws
pressure can be exerted by the mass of the fluids around you
pressure lower and lower will increase because there is more fluids above you, and thus more mass
pascal's law states that a force that operates on a fluid is felt equally throughout the mass
application
we apply these systems and laws daily to make our lives better, but it must also be used with responsibility, as it can hurt the environment
Hydraulic and pneumatic systems, as well as models demonstrating pascal's law use syringes, tubing, water, and air
difference between liquids and gasses
liquids tend to be more dense than their gas counterparts
liquids make hydraulic systems and gasses make pneumatic systems
liquids are less compressible than gasses

density and buoyancy

it can be applied to do things that relate to fluids
an example of an application of this is a hydrometer, which will measure the density of a fluid
buoyancy
an example of this is a fish's swim bladder, which will fill up with water to sink and will be empty to rise
buoyancy is a force that apposes gravity created by fluids and acts on objects

the buoyant force is the force that pushes an object up if it is less dense than the fluid it is suspended in

quantities
all of these measures can be measured, as all matter has these intrinsic properties
Density is the measure of mass per unit volume
volume is the amount of 3 dimensional space an object takes
mass is the amount of matter in an object

fluids on the move

implications of the science
applications

a couple application are blood thinners, turbines, and water purification.

fluid flow is essential for daily life. A lot of society revolves around it.

the types of science

fluids dynamics is the study of how fluids behave.

aerodynamics and hydrodynamics are the study of moving gasses and liquids respectively.

investigating fluids

we can investigate how fluids flow when it's surroundings change.

we can investigate the viscosity and how it's surroundings can affect that.

fluid flow
the viscosity of a fluid is the speed of a fluid when flowing.

viscosity can change with temperature.

a fluid has higher viscosity when it is thicker.

viscosity is also a measure of how thick or thin a fluids is

fluids can have laminar or turbulent flow.

laminar=smooth flow turbulent=rough flow

fluids come in many forms i.e. water is a liquid and air is a gas
properties
fluids have no definite shape.

definitions

extra things I couldn't fit in the rest of this organigram
to streamline is to make an object that will have a natural higher resistance to friction with fluid particles, such as a design for a boat that will cut through water
surface tension is a strong cohesion of particles on the surface of a fluid
valves regulate and modulate the flow of fluids in a system, like in tubing
atmospheric pressure is caused by the mass of the atmosphere above you
adhesion and cohesion is a force between particles of 2 different objects and the strength of that force respectively
main idea's
life is impossible without fluids
fluids have a myriad of different properties
fluids are very important.
Liquids are the state just next to solids, having some potential energy as kinetic energy between the molecules of the substance. It will move to fit it's container. Gas, on the other hand, will take up the most space and the least density. Unlike most liquids, gasses are compressible.
