Characteristic linear dimension L L L (or characteristic length) in the above formulas is a matter of convention. In this calculator, you can choose a particular substance from some examples we have prepared or enter your own fluid parameters. ν \nu ν - Kinematic viscosity of a fluid ( ν = μ / ρ \nu = \mu / \rho ν = μ / ρ).μ \mu μ - Dynamic viscosity of a fluid and.L L L - Characteristic linear dimension.u u u - Velocity of fluid (with respect to the object).Although the Reynolds number can be defined in several different ways, it remains a non-dimensional factor. If you want to learn more about fluid viscosity, you should check out Stokes' law calculator, where you can find, among others, viscosity definition. The Reynolds number definition generally includes the velocity of a fluid, the characteristic length (or characteristic dimension), and the properties of the fluid, such as density and viscosity. On the other hand, viscous forces counteract this effect and progressively inhibit turbulence. On one hand, inertial forces generate fluid friction which is a factor in developing turbulent flow. The Reynolds number is the ratio of inertial forces to viscous forces exerted on a fluid that is in relative motion to a surface. For example, if you want to compare a small-scale model (e.g., a model of an airplane) with a real situation, you should keep the Reynolds number the same. Reynolds number is one of the characteristic numbers used in fluid dynamics to describe a character of the flow. They can be very useful in analyzing fluid motion. Using this calculator, you will also find some examples of calculations that can be done with the Reynolds number formula.Īre you interested in fluid mechanics? You should also check our buoyancy calculator or Bernoulli equation calculator. Read on to find out what are the laminar flow and turbulent flow Reynolds numbers. In the following text, we have provided the Reynolds number equation, units discussion, and a comparison of laminar and turbulent flows. It can describe liquid flow in a pipe, flow around airfoils, or an object moving in a fluid. The Reynolds number has broad applications in real life. Keep reading if you want to find the answers to these questions: This factor measures the ratio of inertial forces to viscous forces occurring during the fluid movement. Lone pairs of valence electrons are at the other two corners, which do not engage in the bonding.With our Reynolds number calculator, you can quickly compute the Reynolds number that helps predict whether the flow of a liquid will be laminar or turbulent. The atoms of hydrogen are similar to the two corners of the oxygen-centered tetrahedron. The hydrogen atoms in a water molecule form a 104.5 ° angle with the oxygen atom.These elements are known to form hydroxides upon reacting with water, releasing hydrogen in the process. Hydrogen is displaced from water by metallic elements that are more electropositive than hydrogen, particularly alkali metals and alkaline earth metals such as sodium, lithium, potassium, cesium, and calcium.This process is generally referred to as electrolysis. By running an electric current through it, liquid water can be divided into the elements hydrogen and oxygen.The electrical conductivity of pure water is low and it is known to increase with the dissolution of a small amount of ionic content, such as sodium chloride.Under ordinary conditions, the compressibility of liquid water varies from 4.4*10 -10 Pa -1 to 5.1*10 -10 Pa -1. For most purposes, liquid water may be considered to be incompressible. ![]() The values of the dynamic viscosity of water at certain temperature ranges have been tabulated below. the viscosity of water decreases as the temperature is increased. It can be noted that the viscosity of water increases as the temperature is decreased. The SI unit for dynamic viscosity is pascal-second (Pa.s) or newton-second per metre squared (N.s/m 2). Therefore, it can be understood that the viscosity of syrups and honey will be higher than the viscosity of water. For liquids such as water, viscosity can be perceived as a measure of the liquid’s resistance to flow. Viscosity is a measure of the resistance of a fluid to deformation at a given rate. The viscosity of water at a temperature of 20 degrees Celsius is approximately 0.01 poise or 10 -3 Pa.s (Pascal seconds). Viscosity of Water What is the Viscosity of Water?
