TOP 50 Fluid Mechanics Quiz and Answers

You may already know about the importance of Fluid Mechanics in science and engineering. Maybe you’ve even heard of Fourier’s Law, or respect this field as it should be respected by every engineering student. But do you really know everything there is to know about this subject? Do you really understand how turbulence affects heat conduction in a fluid environment? And what can you tell the people at your office whenever they say “I could never have anything to do with this subject?” These Fluid Mechanics Quiz and Answers are composed by our Livemcqs team.

What are the two types of fluid mechanics?

The different types of fluid flow are: Steady and Unsteady Flow. Uniform and Non-Uniform Flow.

What do you mean by fluid mechanics?

Fluid mechanics is the study of fluid behavior (liquids, gases, blood, and plasmas) at rest and in motion. Fluid mechanics has a wide range of applications in mechanical and chemical engineering, in biological systems, and in astrophysics.

What are the 4 properties of fluids?

Temperature, density, pressure, and specific enthalpy are the thermodynamic properties of the fluids.

Is fluid mechanic hard?

Fluid mechanics isn’t any harder than solid mechanics or any other subject that utilizes partial differential equations. Fluid mechanics isn’t any harder than solid mechanics or any other subject that utilizes partial differential equations.
