Understanding Bernoulli's Equation

What happens to the speed of a fluid when the cross-sectional area of the pipe it flows through is reduced?

• The speed increases.

• The speed decreases.

• The speed fluctuates randomly.

• The speed remains constant.

According to Bernoulli's principle, what happens to the pressure of a fluid as its speed increases?

• The pressure increases.

• The pressure decreases.

• The pressure remains constant.

• The pressure becomes zero.

Which equation is used to relate the pressure, speed, and kinetic energy of a fluid?

• Continuity equation

• Bernoulli's equation

• Newton's second law

• Ideal gas law

In a fluid system, if the height increases, what happens to the pressure?

• The pressure decreases.

• The pressure remains constant.

• The pressure becomes zero.

• The pressure increases.

What is the effect on fluid pressure when the cross-sectional area of the pipe is doubled?

• The pressure becomes zero.

• The pressure increases.

• The pressure remains constant.

• The pressure decreases.

What is the relationship between pressure and elevation in a fluid system?

• Pressure is higher at higher elevations.

• Pressure is lower at higher elevations.

• Pressure fluctuates randomly with elevation.

• Pressure is constant regardless of elevation.

How does Bernoulli's equation account for changes in both kinetic and potential energy?
