This water viscosity calculator will assist you in determining the viscosity of water at room temperature, as well as any other temperature, including those exceeding 300 °C! Learn about the absolute viscosity of water (also known as dynamic viscosity) and how to convert it to kinematic viscosity with this calculator. You'll also learn how to use a variety of methods to calculate water viscosity and the effect of temperature on water viscosity.

### What Does Water's Viscosity Mean?

The viscosity of water is defined as the reluctance of water to flow. To put it another way, viscosity is a fluid attribute that refers to the thickness of a liquid such as water. It is the interaction of various molecules in water at the molecular level.

In most cases, viscosity is expressed in Newton Seconds per metre square or Pascal Seconds per metre square (Pa s). Keep in mind that the viscosity of water is always inversely proportional to its temperature. When the temperature rises, the viscosity of water reduces; when the temperature falls, the viscosity of water increases. Because all fluids have different viscosity and density values, water viscosity is commonly used as a benchmark for all liquids; for liquids, it is generally classified as low or high.

### Types of Viscocity

Viscosity is defined as the friction that exists between the molecules of a fluid in motion. The viscosity of a liquid can be measured using one of two methods:

1. Kinematic Viscosity
2. Dynamic Viscosity

Kinematic Viscosity: The value of internal resistance of liquids during flow under the force of gravity is known as kinematic viscosity. It was measured using an online kinematic viscosity calculator, which calculated the time in seconds required for a fixed volume of liquids to flow a certain distance using gravity via the capillaries within the viscometer at a given temperature.

Dynamic Viscosity: The tangential force per unit area required to move liquids in the horizontal plane with unit viscosity is called dynamic viscosity. Absolute viscosity of liquids is another name for dynamic viscosity.

Viscosity was first measured in the 1800s using capillary tube methods. The viscosity is measured using a variety of devices and techniques.

• Capillary Viscometer
• Falling Sphere Viscometer
• Zahn Cup
• Rotational Viscometer
• Vibrational Viscometer

### Water's Viscosity at Different Temperatures

 Temperature [°C] Viscosity [mPa·s] 10 1.308 20 1.002 30 0.7978 40 0.6531 50 0.5471 60 0.4658 70 0.4044 80 0.3550 90 0.3150 100 0.2822

### Water's Kinematic and Dynamic Viscosity in SI Units

 Temperature – t – (°C) Dynamic Viscosity – µ – (N s/m2) x 10-3 Kinematic Viscosity -ν – (m2/s) x 10-6 0 1.787 1.787 5 1.519 1.519 10 1.307 1.307 20 1.002 1.004 30 0.798 0.801 40 0.653 0.658 50 0.547 0.553 60 0.467 0.475 70 0.404 0.413 80 0.355 0.365 90 0.315 0.326 100 0.282 0.294

### What is the Purpose of Viscosity Evaluation?

The makers will be able to estimate how the elements will behave in the actual world if the viscosity data of the materials is calculated. For example, if toothpaste does not have the correct viscosity value, pumping the toothpaste out of the tube will be extremely difficult. You can properly design the transportation and product process if you know the exact value of viscosity for each given substance.

### How do I use our water viscosity calculator?

To use our calculator, start by entering the temperature at which you'd like to calculate the water viscosities. You may also see the viscosity values at any temperature by moving your mouse over (on PCs) or dragging (on mobile phones) the chart in our calculator. As a bonus, we added water density estimates at any temperature to our water viscosity calculator.

### FAQs on Water Viscosity Calculator

1. What is meant by Viscocity?

The resistance of a fluid to flow is measured by its viscosity. The slower a fluid flows over a surface, the higher its viscosity. For example; Maple syrup and honey have a high viscosity and flow slowly, making them liquids with a high viscosity. Liquids with low viscosities, such as water and alcohol, flow freely and have low viscosities.

2. What can I do to make water more viscous?

To increase the viscosity of the water, set it to a very low temperature. Water molecules lose energy when the temperature drops, causing them to pile up close together. The water molecules encounter increased friction against each other as a result of the piling up, causing them to flow slower or become viscous.

3. What effect does sugar have on water viscosity?

The viscosity of water is increased by adding compounds that thicken water, such as sugar. The more sugar added to the water, the more viscous and thicker it becomes. The addition of heat to the mixture will aid in the incorporation of more sugar into the water. The combination will become more viscous as it cools to room temperature, as opposed to when it is still hot.

4. Is there a relationship between salt and water viscosity?

Water viscosity rises when salt is added to it. The viscosity of a solution increases when salt is added to it because it thickens and densifies it. When comparing saltwater to freshwater, it may not be readily apparent, but it will be obvious with larger salt concentrations.

5. Is it true that gases have viscosity?

Gases, like liquids, have viscosity. However, unlike liquids, the viscosity of gases is affected by temperature, therefore at greater temperatures, the viscosity of gases increases as well. In other words, as the temperature rises, gases such as air become more stagnant than when the temperature falls.
