![]() ![]() Turbulence also leads to edgy currents in which different sub-flows intersect or even move counter to the overall flow direction. One interprets the Reynolds number as such: a low Reynolds number suggest the flow should be dominated by laminar (sheet-like) flow at high Reynolds numbers one expects significant turbulence due to the differences in the fluid's speed and direction. At larger scale it has uses in meteorology and climatology. In practical applications the ability to predict when a turbulent flow will appear is important in designing piping systems, airplane wings, aerodynamic vehicles, including for scaling from study models to actual aircraft/vehicle. It can also be used to study and predict hot gases as in a flame in air. The number sees uses in fluid mechanics where it is used to predict flow patterns in different fluid flow scenarios. Knowing Re one can anticipate the transition from laminar to turbulent flow which is the main utility of a Reynolds Number calculator. The Reynolds number (Re) is a dimensionless quantity for dynamic similarity and is calculated as the ratio of inertial forces to viscous forces of a flow of liquid. ![]() The Reynolds Number calculator will then apply the relevant equation and produce the Reynolds Number (Re) as result. compressible gases) and fluids of variable viscosity (non-Newtonian fluids). Special consideration should be taken for fluids of variable density (e.g. the inner diameter of a pipe, the diameter of a sphere moving in liquid, or the length of a plate over which the substance is flowing. Finally, enter the characteristic length, e.g. Then enter the velocity at which the substance is moving. m 2/s, Stokes and centiStokes for kinematic viscosity, imperial and metric/scientific units for density, velocity and length).įirst, select whether you know the substance's kinematic viscosity or the dynamic viscosity and density and then enter the quantities you know. It supports a wide range of input and output measurement units (e.g. Ν = kinematic viscosity = 235, μ = dynamic viscosity = 2472, ρ = density of fluid =?With the help of this calculator you can compute the Reynolds Number of a liquid or gas. Ν = kinematic viscosity = 15, μ = dynamic viscosity = 105, ρ = density of fluid =?įind the density of the fluid if the kinematic viscosity of the fluid is 235 m 2/s -1 and the dynamic viscosity is 2472 Ns/m 2. Put the values in the above formula and simplify carefully.įind the density of the fluid if the kinematic viscosity of the fluid is 15 m 2/s -1 and the dynamic viscosity is 105 Ns/m 2. Ν = kinematic viscosity of the fluid, μ = dynamic viscosity of the fluid, ρ = density of the fluid Write the formula of the density with detail. ![]() Ν = kinematic viscosity = 11, μ = dynamic viscosity = 55, ρ = density of fluid =? Write the data carefully from the given situation. Formula:įind the density of the fluid if the kinematic viscosity of the fluid is 11 m 2/s -1 and the dynamic viscosity is 55 Ns/m 2. While dynamic viscosity measures the resistance to flow under applied shear stress and kinematic viscosity considers the ratio of dynamic viscosity to the fluid's density. Viscosity can vary with the increase or decrease of temperature, pressure, and the presence of impurities. While, if the forces are weak then it shows its viscosity is very low and the flow rate is high. When the cohesive forces are very strong then the viscosity of the fluid is very high and its flow rate is very low. It is present in fluids and gases due to the cohesive forces between molecules. On the other hand, viscosity is a property of fluids as well as liquids and gases. It also tells how much fluid is poured and how to respond when external force is applied to it. Viscosity is the resistance of the fluid that is felt in its flow freely. Density is the property of the fluid which tells how much the fluid is viscous or how fast it flow. Kinematic Viscosity Calculator is a tool that is used to find the density of the fluid by using the kinematic and dynamic viscosity of the fluid. ![]()
