Chapter 1 Flashcards
Viscosity?
The stickiness of a fluid
Calibrated Air Speed
CAS
Is ISA corrected for instrumental error and predictable pressure errors
Equilivant Air Speed
EAS
Equilivant airspeed is CAS corrected for compressibility. This provides the most accurate indication of dynamic pressure
What is a fluid
A liquid or a gas that has an ability to flow
Static pressure
A force acting over an area and is measured in newtons per square metre. It is represented by the Greek symbol p
Newton’s first law
A body will remain at rest or in uniform motion unless acted upon by an external force
Newton’s second law
The acceleration of a body in a straight line is proportional to the applied force and inversely proportional to the mass of the body
Newton’s third law
To each and every action there is an equal reaction opposite
What is the rate of doing work a description of?
Power
What is the work formulae
Work = force x distance
Pressure energy
The energy contained in the billions of molecules that make up a volume of air
Kinetic energy
The energy which a mass possesses due to its relative motion
Force formula
F = m x a
F in newtons
Mass in KG
Acceleration in m/s2
Momentum formula
P =mv
Power formula
Power = work/time
