Principles of Flight 2

What is the relationship between Bernoulli’s principle and flight?

• It helps in understanding the process of flight

• It explains the structure of aircraft

• It describes the history of aviation

• It defines the types of engines used in aircraft

What happens to the speed of a fluid as it goes through a convergent duct?

• It decreases

• It remains constant

• It increases

• It stops

What is subtracted from the total pressure to find dynamic pressure?

• Static atmospheric pressure

• Temperature

• Humidity

• Altitude

What does the symbol 'v' represent in the context of flight principles?

• Air density

• Relative air velocity

• Atmospheric pressure

• Temperature

What type of energy is specifically focused on in the principles of flight?

• Thermal energy

• Chemical energy

• Kinetic energy

• Electrical energy

Which of the following is NOT a result of the venturi effect?

• Increased fuel efficiency

• Reduced pressure

• Increased velocity

• Increased temperature

What is the result of higher pressure on the lower side of an aerofoil?

• Increased drag

• Decreased lift

• Resultant force called lift

• Constant pressure

Which factor affecting lift involves the physical dimensions of the wing?

• The speed of the wing through the air

• The density of the air

• The size of the wing

• The angle of attack
