WHAT IS FLUID MECHANICS ? FLUIED: Any thing whose particles can move easily from one place to another that means shape can be easily changed upon the application of negligible force. MECHANICS: Study of response of bodies upon the application of force. FLUID MECHANICS : Fluid mechanics may be defined as the branch of engineering science which deal with behavior of fluids under the condition of rest and

Drunk driving “Please blow into this machine. Thank you.” If you are a driver‚ this sentence is familiar to you. Many police examine drunk driving at the crossroads every day. Meanwhile‚ numbers of advertisements and messages on TVs and radios persuade us not to drive after drinking. Driving without drinking has become a common understanding. But why do we have to accept this? And what would we do if somebody is drunk driving? Today‚ I hope to convince you that drunk driving is terrible and that

CEIC2001 – Fluid Mechanics Notes Fluid – A substance which is capable of flowing. A fluid is also a substance which has no permanent resistance to change in shape i.e. a solid can resist a shear stress‚ τ by static deflection; a fluid cannot‚ any shear stress applied to a fluid will result in the motion of that fluid for as long as the shear stress is applied. τ=FA Where F = force which is tangent to a surface (shear force)‚ A = area of moving plate in which shear force is applied to.
