Continuum Hypothesis in Fluid Mechanics The macroscopic behavior of fluids makes them appear to be continuous. However‚ when viewed at the microscopic scale fluids cannot be viewed as continuous. The fluid under consideration will have molecules bombarding each other. It is not possible to declare the fluid velocity at a point as there is no guarantee that the fluid molecules are present at that point at a particular instant of time. When we calculate the fluid velocity or density at a point it

A dialect continuum is a range of dialects spoken across a large geographical area‚ differing only slightly between areas that are geographically close to each other‚ and gradually decreasing in mutual intelligibility as the distances become greater. Dialects separated by great geographical distances may not be mutually comprehensible. According to the Ausbausprache - Abstandsprache - Dachsprache paradigm‚ these dialects can be considered Abstandsprachen (i.e.‚ as stand-alone languages). However

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.

knuckles. Learn your MATH !!! You will need to be able to work with numbers including decimals‚ fractions and both standard & metric units of measurement as well for most all aspects of automotive repair‚ including electronics. Being an automotive mechanic can be a very rewarding career if you like challenges and the sense of pride in doing the job right the first time as people’s lives may depend on the quality of your workmanship. If you decide against this as a career‚ it also pays to learn as much
