Aerodynamics and Hydrodynamics

Question 1

What is aerodynamics?

Answer 1

How moving air interacts with moving solid objects

Question 2

What are the four forces that apply in aerodynamics?

Answer 2

Weight
Lift
Drag
Thrust

Question 3

What does Bernoulli’s Principle state?

Answer 3

An increase in speed of fluid occurs at same time as a decrease in pressure or fluid’s potential energy (due to the law of conservation of energy)
(aka speed ↑ = pressure ↓, and vice versa)

Question 4

What is the equation for flow rate?

Answer 4

Q = V x t
flow rate = velocity x time

Question 5

What is the difference between flow rate and flow velocity?

Answer 5

Flow rate shows volume of fluid in given time, flow velocity shows distance fluid covers in given time

Question 6

What is the equation for flow velocity?

Answer 6

V = vA
flow velocity = volume x area

Question 7

What do you do to Bernoulli’s Principle to make it useable?

Answer 7

Bernoulli’s Principle as given, then equals the same thing but all 1s are switched for 2s
