Fluid Mechanics Quiz

Which of the following best describes fluid mechanics?

• The examination of electrical properties in liquids.

• The study of the behavior of fluids at rest and in motion.

• The study of solid materials under stress.

• The analysis of thermal dynamics in gases.

Why is understanding fluid mechanics important in engineering?

• It helps in designing structures and predicting natural phenomena.

• It has no practical applications.

• It is only relevant for studying gases.

• It focuses solely on the behavior of solids.

What is a key characteristic of fluids compared to solids?

• Fluids do not deform under stress.

• Fluids maintain a fixed shape.

• Fluids can flow and take the shape of their container.

• Fluids are incompressible.

Which type of fluid is defined as having no viscosity?

• Real fluid

• Ideal fluid

• Non-Newtonian fluid

• Newtonian fluid

Which of the following is a characteristic of real fluids?

• They have no viscosity.

• They flow in parallel layers.

• They are incompressible.

• They exhibit viscosity and compressibility.

What happens to the pressure of a fluid as you go deeper into it?

• It decreases due to reduced weight.

• It increases due to the weight of the fluid above.

• It fluctuates based on temperature.

• It remains the same regardless of depth.

How does pressure in a fluid change with depth?

• It remains constant regardless of depth.

• It decreases with increasing depth.

• It fluctuates randomly.

• It increases with increasing depth due to the weight of the fluid above.

What characterizes laminar flow in a fluid?

• Chaotic changes in pressure and flow velocity.

• Flow in parallel layers with minimal disruption.

• Rapid mixing of fluid particles.

• High turbulence and irregular movement.

Which statement is true about turbulent flow?

• It is always more efficient than laminar flow.

• It occurs when fluid flows in parallel layers.

• It is characterized by chaotic changes in pressure and flow velocity.

• It is only observed in gases.
