Fluids at Rest and in Motion: Comprehensive Assessment

Who originally discovered the principle describing pressure transmission in confined fluids?

• Isaac Newton
• Blaise Pascal
• Albert Einstein
• Galileo Galilei

According to Pascal's Principle, when pressure is applied to a confined fluid, how is that pressure distributed?

• Randomly throughout the fluid
• Only in the direction of applied force
• Equally throughout the entire fluid
• Concentrated at the point of application

In a hydraulic lift system, what happens when a small force is applied to a smaller piston?

• No pressure is transmitted
• Pressure is reduced
• Pressure is transmitted equally to the larger piston
• The system fails to function

What relationship does Bernoulli's Principle describe between fluid velocity and pressure?

• As velocity increases, pressure increases
• As velocity decreases, pressure increases
• As velocity increases, pressure decreases
• No relationship exists between velocity and pressure

Which device uses Bernoulli's Principle to draw fuel into an engine?

• Electric pump
• Carburetor
• Mechanical valve
• Pressure regulator

How does fluid pressure change with depth in a confined fluid?

• Pressure remains constant
• Pressure increases with depth
• Pressure decreases with depth
• Pressure is unrelated to depth

What factor does NOT affect pressure distribution in a confined fluid?

• Fluid depth
• Container shape
• Applied force
• Fluid type

In a hydraulic system, how can a small force create a much larger force?

• By using electrical amplification
• Through pressure transmission
• By changing fluid density
• By heating the fluid

Which practical application demonstrates Bernoulli's Principle in everyday life?

• Refrigeration
• Paint sprayer
• Electric heating
• Mechanical gearing

What happens to pressure when fluid velocity decreases, according to Bernoulli's Principle?

• Pressure remains constant
• Pressure increases
• Pressure decreases
• Pressure becomes zero
