An online water viscosity calculator allows you to find the viscosity, density, dynamic, and kinematic density of water at any temperature. You can get the kinematic viscosity and dynamic viscosity of water by a chart that is provided by the viscosity calculator. Furthermore, you will learn how to find the viscosity of water and the temperature that effects the viscosity of water at room temperature.
In physics, the viscosity of water can be defined as the resistance of a water to flow. In other words, viscosity is a physical property of a fluid that refers to the thickness of a liquid like water. At the molecular level, it is the interaction between different molecules in the water.
Generally, viscosity is measured in Newton Second per meter square or Pascal Second (Pa s). Remember that the water viscosity is always inversely proportional to the temperature. When the temperature increases, the viscosity of water decreases; conversely, if the temperature decreases, then the water viscosity increases.
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.
The viscosity of water can be determined by the following formula:
η = \frac {2ga^2 (∆ρ)} {gv}
Where,
η = viscosity of water
v = velocity of sphere
g = acceleration due to gravity
a = radius of sphere
However, an online Density Calculator allows you to determine the density of an element that is equal to its mass per unit volume.
Example:
Find the viscosity of water at 20 c?
Solution:
The dynamic viscosity calculator provides the density and the viscosity of water at 20 c as follow:
Dynamic viscosity = η = 1.0016 mPa.s
Kinematic viscosity = ν = 1.0034 mm²/s
Density = 0.9982 g/cm³
When you use a dynamic viscosity of water calculator, it also provides viscosity and temperature chart for better understanding:

Calculating the viscosity data of the given materials will helps the manufacturers to predict how the elements behave in the real world. 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. If you know the exact value of viscosity of any material, then you design the transportation and product process precisely.
However, an online Specific Heat Calculator helps to find the heat energy, specific heat, mass of substance, initial, and final temperature of any element.
The viscosity is the friction between the molecules of fluid in motion. There are two different techniques to measure the liquid viscosity as follow:
The kinematic viscosity of fluids is the value of internal resistance of liquids during the flow under the force of gravitation. 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 dynamic viscosity is the tangential force per unit area needed to move the liquids in the horizontal plane with the unit viscosity. Dynamic viscosity is also known as the absolute viscosity of liquids.
First viscosity measurements were made in 1800s using the capillary tube methods. Here are some different instruments and techniques that are used to measure the viscosity.

According 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.
Newton’s Law of Viscosity = τ = η du / dy
Where,
η = Viscosity
τ = Shear Stress
du / dy = Rate of Shear Deformation
A liquid, whose viscosity does not change with shear stain (V/Y), is known as Newtonian Fluid. So, the fluid that follow the newton’s law of viscosity is Newtonian fluid.
A liquid, whose viscosity changes with shear stain (V/Y), is known as NonNewtonian Fluid. Therefore, the fluid that does not follow the newton’s law of viscosity is NonNewtonian Fluid.
An online viscosity calculator will compute the thickness of water at any temperature, even those above the 300 Celsius by following steps:
There is no direct relationship between density and viscosity. However, both density and viscosity are affected by the temperature of liquid.
The graphene is the thinnest fluid that conducts the electricity well and interact with the water in unique ways.
Viscosity is pressure independent, but liquids under the extreme pressure often experience an increase in the viscosity of liquids.
Water is neither basic nor acidic in the nature. It has 7 PH, that makes it a neutral substance.
The water viscosity at the 25 degrees Celsius is roughly equal to \( 10^3 \) Pascal Second or 0.01 Poise.
The kinematic viscosity of water (ν) at 22 degrees Celsius is 0.9565 Milimeter square per second (mm^2 / s).
Water is the universal solvent because it has the ability to dissolve most elements, including sugar, salt, gases, bases, and acids.
Use this water viscosity calculator for determining the viscosities and densities of water at a given temperature. You can also use the water viscosity vs temperature chart or table for finding the effects of temperature on the water viscosity.
