Fluid Dynamics Flashcards
Fluid
Any material that flows
Buoyancy
Upward force of a fluid
Viscosity
Resistance to Flow
Hydrostatic Pressure
Pressure = Force/Area
Why does pressure change as you go lower?
As you go deeper in depth the liquid has a higher weight of everything above it.
Submerged
Completely within the fluid
Hydrostatic pressure
Pressure at a given depth.
Pressure = density * gravity * height
Archimedes’ Principle
Buoyant force is equal to the weight of the fluid displaced by an object.
Weight of object = buoyant force
Neither sink or swim
Weight of object > buoyant force
Sink
Weight of object < buoyant force
Float
Flow Rate
Rate of which a volume flows through a tube
Q = delta V/delta t
Equation of continuity
V1A1 = V2A2
Bernoulli’s Principle
A fluid increases speed when it goes through a narrower space
Bernoulli’s Equation
Relates speed, pressure, and height at any 2 points w/in an ideal fluid
