CE2703 Study Guide - Midterm Guide: Viscosity, Fluid Mechanics, Specific Volume
Document Summary
What is a fluid? a collection of molecules in constant motion. What is density? the amount of matter in an object. What is specific gravity? the ratio of density to water. What is specific volume? the reciprocal of density. What is dynamic viscosity? the friction between the molecule and an object. Conservation of mass, conservation of momentum, conservation of energy. What is conservation of mass? mass can neither be created nor destroyed. What is conservation of momentum? the total momentum of a collision is conserved, the momentum is a constant or unchanging value. 1)viscid (friction) vs. inviscid (frictionless: compressible vs. in compressible. What are the flow regimes? stead, laminar, unsteady, turbulent, transition. What is steady flow? a flow in which conditions may change from point to point but do not change with time. When there is a streamline flow in parallel layers, no eddies.
