Bernoulli's Principle Quiz

Who is Bernoulli's Principle named after?

• A Swiss mathematician named Daniel Bernoulli

• An Italian physicist named Evangelista Torricelli

• A French engineer named Henri Pitot

• A German scientist named Otto Lilienthal

What does Bernoulli's Principle state about the behavior of a fluid?

• An increase in the speed of a fluid occurs with an increase in pressure

• An increase in the speed of a fluid occurs with a decrease in the fluid's potential energy

• An increase in the speed of a fluid occurs with no change in pressure or potential energy

• An increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy

What is a practical application of Bernoulli's Principle mentioned in the text?

• The hydraulic press

• The venturi tube

• The steam engine

• The piston

According to Bernoulli's Principle, what happens to the airflow and pressure past the constriction in a venturi tube?

• The airflow speeds up and the pressure decreases

• The airflow slows down and the pressure increases

• The airflow and pressure both increase

• The airflow and pressure both decrease

What does Figure 1 illustrate?

• The structure of an aircraft's wing at high speed.

• A typical aerofoil cross-section for low-speed flight.

• The internal components of a jet engine.

• The design of a high-speed aircraft fuselage.

What are the pitot tube and static port on an aircraft used for?

• To control the aircraft's altitude.

• To determine the temperature of the air.

• To determine the airspeed of the aircraft.

• To measure the aircraft's weight.

What does the Air Speed Indicator determine?

• The altitude above sea level.

• The dynamic pressure of the airflow past the aircraft.

• The angle of attack of the aircraft's wings.

What is dynamic pressure?

• The difference between altitude pressure and sea-level pressure.

• The difference between the temperature of the air and the aircraft surface.

• The difference between stagnation pressure and static pressure.

• The difference between the lift forces and drag forces on the wings.

What principle is used to calibrate the airspeed indicator?

• Newton's first law of motion.

• Bernoulli's principle.

• Pascal's law.

• The Venturi effect.
