What is the Weight and Density of Water at Known Temperature?Īccording to the Newton’s law of viscosity the shear stress between adjacent layers of liquid is directly proportional to the velocity gradients between the two layers of fluid. Here are some different instruments and techniques that are used to measure the viscosity. Different techniques and Tools to Measure Viscosity:įirst viscosity measurements were made in 1800s using the capillary tube methods. Dynamic viscosity is also known as the absolute viscosity of liquids. The dynamic viscosity is the tangential force per unit area needed to move the liquids in the horizontal plane with the unit viscosity. An online kinematic viscosity calculator measured it by determining the time in seconds that is required for the fixed volume of liquids to flow a known distance by the gravity through the capillaries within the viscometer at a particular temperature. The kinematic viscosity of fluids is the value of internal resistance of liquids during the flow under the force of gravitation. There are two different techniques to measure the liquid viscosity as follow: The viscosity is the friction between the molecules of fluid in motion. However, an online Specific Heat Calculator helps to find the heat energy, specific heat, mass of substance, initial, and final temperature of any element. If you know the exact value of viscosity of any material, then you design the transportation and product process precisely. For example, if the toothpastes do not have the true value of viscosity, then it will be too difficult to pump out the toothpaste from the tube. Kinematic and Dynamic Viscosity of Water in SI Units:Ĭalculating the viscosity data of the given materials will helps the manufacturers to predict how the elements behave in the real world. (Image) The viscosity of Water at Different Temperature: When you use a dynamic viscosity of water calculator, it also provides viscosity and temperature chart for better understanding: The dynamic viscosity calculator provides the density and the viscosity of water at 20 c as follow: However, an online Density Calculator allows you to determine the density of an element that is equal to its mass per unit volume. The viscosity of water can be determined by the following formula: Mostly, the water viscosity is used as a benchmark for all liquids because all fluids have particular values of viscosity and density for liquids, it is generally considered low or high. When the temperature increases, the viscosity of water decreases conversely, if the temperature decreases, then the water viscosity increases. Remember that the water viscosity is always inversely proportional to the temperature.
Generally, viscosity is measured in Newton Second per meter square or Pascal Second (Pa s). At the molecular level, it is the interaction between different molecules in the water. In other words, viscosity is a physical property of a fluid that refers to the thickness of a liquid like water. In physics, the viscosity of water can be defined as the resistance of a water to flow.

Furthermore, you will learn how to find the viscosity of water and the temperature that effects the viscosity of water at room temperature. You can get the kinematic viscosity and dynamic viscosity of water by a chart that is provided by the viscosity calculator.
An online water viscosity calculator allows you to find the viscosity, density, dynamic, and kinematic density of water at any temperature.
