REYNOLDS NUMBER
Definition
A <REYNOLDS NUMBER>, in fluid mechanics, is a <Property> that is a criterion of whether fluid (liquid or gas) flow is absolutely steady (streamlined, or laminar) or on the average steady with small unsteady fluctuations (turbulent). It is calculated as: Re = rho.v.l/eta = v.l/nu where rho is the volumetric mass, v is <SPEED>, l is <LENGTH> , eta is dynamic viscosity and nu kinematic viscosity
