Fluid dynamics The study of fluids at motion. Stream line flow Claminar plow) x The regular steady flow of fluicis. The velocity of all fluidp- articles slowing through a
common point will be same. It f allows a definite path. Turbu lent slow The irregular and unsteady flaw of fluid at common At common point velocity will be different. Reynold's number(Re) & The dimensionless number which decides the flowis stre- am line or turbulent. Re = PVD g =Density n V= velocity D= Diameter of pipe n = coeffecien of viscocity . m Re3000 Turbulent Re 2000 b/w 3000 unsteady. If density is less, verocity is less, diameter of pipe is less and it PS more viscous. Therflow is famina. * if denisity is high, velocity is high , / clancer of pipe ishigh an ait is more viscous. The slow is less Turcelest.
