Fluids And Pressure Flashcards
Equation for pressure
Area
Equation for density is
Volume
SI unit for force force is measured by
Newtons
aera is measured in
Meters squared
Bernoullis principle
The faster a fluid moves the less pressure fluid exerts or as the speed of the moving fluid increases the pressure within the moving fluid increases
Pascals principle
Dates that the change in pressure at any point in an enclosed fluid will be transmitted equally to all parts of that fluid
Archimedes principle
states that the buoyancy force on an object in fluid Is equal to the weight that the fluid is displacing
Hydraulic system
Hydrolic systems multiply forces and it transmits pressure through an enclosed fluid system
Density
is the amount of mass in a given volume
Density =mass/volume
Atmospheric pressure
The pressure caused by the weight of the atmosphere
Buoyant force
The upward force in a liquid
Fluid
A non soils state of matter in which the atoms or molicuses are free to move
Liquids and gasses
Air pressure
The pressure exerted by the atmosphere
Drag
A force that opposes or restricts Motian
Why do all fluids exert pressure
All the particles combined to make a pressure. The particles collide
with one another
What kind of moving air on the wing causes lift
Slow moving aur
What happens if you blow two objects that are hanging together
They will come closer together
If an object is Dencer than one another what will happen if you combine them
The lighter one will float and the Dencer one will sink
What cause objects to feel lighter in water
When the weight of the object is less than the buoyancy force
Air pressure at higher elevations is what
Lower
Why are bubbles round
Because fluids exert pressure In all directions so it ends up being round
Why do bubbles rise
Cuz their less dence than air
If I had a boat and loaded it with cargo how would I determine the total boyancy acting on the object
The weight of the boat plus the weight of the cargo equals the boyancy force
What makes a siphon successful
If the one that’s sending is higher
The tube has to be hooked shaped
Low pressure has to be in the tube
