Fluid Dynamics
refers to the flow of liquids and gases
The study of the flow of liquids is referred to as
Hydrodynamics
The study of the flow of gases is referred to as
Aerodynamics
There are __ main types of flows that exist in Fluid Dynamics
2
Types of flows in fluid dynamics
Laminar and Turbulent flow
Laminar Flow
Laminar Flow allows for gases and liquids to move with little disturbance to the flow
Turbulent Flow
occurs when there are disturbances to how the gases or liquids flow, usually as they try to flow around solid objects
As a baseball travels through the air, it creates ___as the ball cuts through the air
turbulence
Bernoulli’s Principle
states that the speeds of flows will change the pressure of the flows
winged flight relies of this pressure difference to allow for ___
lift
Is Air Pressure higher or lower in your Lungs as you inhale?
lower
Fluid Pressure
The pressure found in Liquids and Gases rely on whether or not the liquid or gas enclosed

Open Condition
Fluids that are in an Open Condition follow
_____
Fluid Static Principles
If the fluid is enclosed, it is considered to be in a
____
closed condition
Fluids in a closed condition generally follow
____
Pascal’s Law of Fluid Pressure
What is the name of the outermost layer of Earth’s Atmosphere?
The Exosphere is roughly 700 kilometres to possibly 190 000 kilometres away from the Earth’s Surface
Air Pressure will ____ if an object is ____ to the
Earth’s Core
Air Pressure will increase if an object is closer to the Earth’s Core
The Earth’s Rotation can create a _____ where greater Centrifugal Force will decrease the Air Pressure normally
