Hydraulic diameter - d h - (or c haracteristic length - L) (m, ft)Ībsolute (dynamic) viscosity - μ - (Ns/m 2, lb m/s ft) The calculator is generic and can be used for metric and imperial units as long as the use of units are consistent. The calculator is valid for incompressible flow - flow with fluids or gases without compression - as typical for air flows in HVAC systems or similar. This calculator can be used if density and absolute (dynamic) viscosity of the fluid is known. Online Reynolds Calculator Density and absolute (dynamic) viscosity is Known free apps for offline use on mobile devices. Reynolds Number can then be calculated using equation (1) like Example - Calculate Reynolds NumberĪ Newtonian fluid with a dynamic or absolute viscosity of 0.38 Ns/m 2 and a specific gravity of 0.91 flows through a 25 mm diameter pipe with a velocity of 2.6 m/s.ĭensity can be calculated from the specific gravity of the fluid and the density of the specific gravity reference water 1000 kg/m 3 - as In practice laminar flow is only actual for viscous fluids - like crude oil, fuel oil and other oils. The Reynolds Number can be used to determine if flow is laminar, transient or turbulent. Ν = kinematic viscosity (cSt) (1 cSt = 10 -6 m 2/s ) The Reynolds number for a pipe or duct expressed in Imperial units The Reynolds Number for the flow in a duct or pipe can with the hydraulic diameter be expressed asĭ h = hydraulic diameter (m, ft) Reynolds Number for a Pipe or Duct in Imperial Units Ν = μ / ρ = kinematic viscosity (m 2/s, ft 2/s) Reynolds Number for Flow in Pipe or Ductįor a pipe or duct the characteristic length is the hydraulic diameter. Μ = dynamic viscosity (Ns/m 2, lb m/s ft) U = velocity based on the actual cross section area of the duct or pipe (m/s, ft/s) Reynolds Number can therefore be expressed as dynamic pressure (ρ u 2) to shearing stress (μ u / L).inertia force (ρ u L) to viscous or friction force (μ).Oxygen dynamic and kinematic viscosity at atmospheric pressure and varying temperature:ĭynamic viscosity of oxygen at varying temperature and 1, 10, 50 and 100 bara (14.Reynolds Number - the non-dimensional velocity - can be defined as the ratio See also other properties of Oxygen at varying temperature and pressure: Density and specific weight and Specific heat (heat capacity), and Thermophysical properties at standard conditions,Īs well as dynamic and kinematic viscosity of air, ammonia, benzene, butane, carbon dioxide, ethane, ethanol, ethylene, methane, methanol, nitrogen, propane and water. While the kinematic viscosity is given as cSt, m 2/s, and ft 2/s The output dynamic viscosity is given as Pa*s, N*s/m 2, cP, mPa*s, lb f*s/ft 2 and lb m/(ft*h), The calculator below can be used to estimate oxygen dynamic or kinematic viscosity at given temperatures and atmospheric pressure. Oxygen phase diagram Online Oxygen Viscosity Calculator Tabulated values and viscosity units conversion are given below the figures. Absolute or dynamic viscosity is used to calculate Reynold's Number to determine if a fluid flow is laminar, transient or turbulent. The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress.įor further definitions, go to Absolute (dynamic) and kinematic viscosity.
