1Fluids are [blank_start]materials[blank_end] that have [blank_start]no fixed shape[blank_end] and are [blank_start]free to flow[blank_end], such as [blank_start]liquids[blank_end] and [blank_start]gases[blank_end].
- Amaterials
- Bliquids
- Cgases
- Dfree to flow
- Eno fixed shape
2Laminar flow is a type of [blank_start]fluid flow[blank_end] where the fluid travels [blank_start]smoothly[blank_end] or in [blank_start]regular paths[blank_end].
- Afluid flow
- Bsmoothly
- Cregular paths
3Turbulent Flow is a type of [blank_start]fluid flow[blank_end] where the fluid undergoes [blank_start]irregular[blank_end] [blank_start]fluctuations[blank_end] and [blank_start]mixing[blank_end].
- Afluid flow
- Birregular
- Cfluctuations
- Dmixing
4Flow rate is a [blank_start]measure[blank_end] of how [blank_start]quickly[blank_end] fluids move and is [blank_start]measured[blank_end] in a [blank_start]volume[blank_end] per [blank_start]unit time[blank_end].
- Ameasure
- Bquickly
- Cmeasured
- Dvolume
- Eunit time
5Viscosity is a [blank_start]measure[blank_end] of a fluid's [blank_start]resistance[blank_end] to flow.
- Ameasure
- Bresistance
6Cohesion is a [blank_start]measure[blank_end] of how [blank_start]strongly[blank_end] a fluid's particles [blank_start]attract[blank_end] each other.
- Ameasure
- Btype
- Claw
- Dstrongly
- Efast
- Fattract
- Gpush
- Hfind
7Adhesion is the [blank_start]attraction[blank_end] between the particles of one [blank_start]substance[blank_end] and the particles of another substance.
- Aattraction
- Bratio
- Cfriction
- Dsubstance
- Efluid
- Fgas
- Gsolid
8Volume is the [blank_start]amount[blank_end] of [blank_start]space[blank_end] a [blank_start]substance[blank_end] takes up.
- Aamount
- Bspace
- Csubstance
9Mass is the amount of [blank_start]matter[blank_end] that makes up a [blank_start]substance[blank_end].
- Amatter
- Bsubstance
10Weight is the force of [blank_start]gravity[blank_end] acting on a [blank_start]substance[blank_end]. The average force of [blank_start]gravity[blank_end] on planet Earth is about [blank_start]9.81[blank_end] m/s^2
- Agravity
- Bsubstance
- Cgravity
- D9.81
11Density is a measure of the [blank_start]mass[blank_end] per [blank_start]unit volume[blank_end] of a substance. Density = [blank_start]Mass[blank_end] / [blank_start]Volume[blank_end]
- Amass
- Bunit volume
- CMass
- DVolume
12Factors that affect Flow Rate:
- The t[blank_start]ype of fluid[blank_end]
- The f[blank_start]orce pushing on the fluid[blank_end]
- The [blank_start]size of the opening[blank_end] the [blank_start]fluid is flowing through[blank_end]
- The [blank_start]type of surface[blank_end] over which [blank_start]the fluid is flowing[blank_end]
- The te[blank_start]mperature of the fluid[blank_end]- Asize of the opening
- Bfluid is flowing through
- Ctype of surface
- Dthe fluid is flowing
- Eype of fluid
- Force pushing on the fluid
- Gmperature of the fluid
135 Main Points Of The Particle Theory
- All matter [blank_start]consists of particles[blank_end]
- Particles are always [blank_start]moving[blank_end]
- Particles always have [blank_start]space[blank_end] between them
- Particles move [blank_start]faster[blank_end] and [blank_start]spread[blank_end] farther apart when they are [blank_start]heated[blank_end]
- Particles [blank_start]attract[blank_end] each other- Aconsists of particles
- Bmoving
- Cspace
- Dfaster
- Espread
- Fheated
- Gattract
14Temperature up = [blank_start]Flow rate[blank_end] up
- AFlow rate
15Archimedes Principle
Any [blank_start]substance[blank_end] completely or partially [blank_start]submerged[blank_end] in a fluid at rest ([blank_start]neutral buoyancy[blank_end]) is acted upon by an upward buoyant force equal to the [blank_start]weight[blank_end] of the submerged substance.- Asubstance
- Bsubmerged
- Cneutral buoyancy
- Dweight
16Buoyancy is the upward force that a [blank_start]fluid[blank_end] exerts on a substance. It determines whether the substance [blank_start]sinks[blank_end] or floats. The buoyant force is measured in [blank_start]Newtons[blank_end].
- Afluid
- Bsinks
- CNewtons
17A pneumatic system is a system that uses [blank_start]gases[blank_end] under [blank_start]pressure[blank_end].
- Apressure
- Bgases
18A hydraulic system is a system that uses [blank_start]liquids[blank_end] under [blank_start]pressure[blank_end].
- Aliquids
- Bpressure
19Pascal's Law Part 1 states that at [blank_start]any[blank_end] point in a fluid at [blank_start]rest[blank_end], the [blank_start]pressure[blank_end] is the same in every [blank_start]direction[blank_end].
- Aany
- Brest
- Cpressure
- Ddirection
20Pascal's Law Part 2 states that when [blank_start]pressure[blank_end] is applied to a fluid, the pressure changes by the [blank_start]same[blank_end] amount at [blank_start]all[blank_end] points in the fluid.
- Apressure
- Bsame
- Call
21Temperature Up = Pressure [blank_start]Up[blank_end] Temperature [blank_start]Down[blank_end] = Pressure Down
Volume Down = Pressure Up Volume Up = Pressure [blank_start]Down[blank_end]
Pressure Up = Volume [blank_start]Down[blank_end] Pressure Down = Volume Up- AUp
