You'd get the volume by reading the marking on your graduated cylinder. You can easily get the mass of the liquid by subtracting the weight of the graduated cylinder from the total weight.

Next, calculate the liquid's density with the same equation from above. Find the 'r' (radius) by measuring the length of the middle of the ball, then dividing by 2. So first, you'll need to weigh the ball to get the mass in kilograms. The equation is this: ρ = m / v (mass = mass / volume). You'll need to first find out how dense your ball is. To calculate the viscosity of a liquid, you'll need a ball, the liquid itself, and a graduated cylinder. It sounds simple, but there's quite a bit that goes into getting the final calculation. On the most basic level, viscosity is the shear stress divided by the shear rate. Now that you've learned a bit about what viscosity is, we can move onto the calculations. But if the viscosity is too high, then they'll have a tough time getting the product out. If the viscosity is too low, then the toothpaste will be runny when the customer squeezes the tube. Without that data, you risk spoilage of materials or bad user experience.įor example, toothpaste is a liquid that needs to have just the right viscosity for a good user experience. Considering viscosity is not a static thing, it's crucial you know exactly how a material will change when you heat it up or cool it down. The main benefit of calculating the viscosity of different materials is so you know the optimal way to store it. Usually, this means if you want to get a material flowing, you'll have to heat it up, and if you want it to stop flowing, you'll have to cool it down. And the colder a liquid is, the more viscous it'll be. In general, the hotter a liquid is, the less viscous it'll be. But another important factor is temperature. Obviously, the properties of the material itself will affect its viscosity. So with the hair gel example, it has high viscosity because it's very resistant to flow and has high internal friction.

Viscosity measures a liquid's resistance to flow essentially, it's how much internal friction there is in it. That's the right idea, but let's delve a little bit deeper. At a basic level, you probably know it's how thick or thin a liquid is.

We'll give you all the information you need to ensure better product viscosity.īefore we show you how to calculate viscosity, you'll have to first understand what it is. If you're wondering how to calculate viscosity so you can have better control over your materials, then keep reading. In order to keep your materials at the right viscosity, you'll need to make the right calculations and have control over the storage parameters, such as the temperature. This is because it has high viscosity.Īs you may guess, viscosity is highly important for a range of products without the right viscosity, you may get product waste. When you get up in the morning and squeeze some hair gel into your hand, you may notice that no matter which way you turn your hand, the gel doesn't really go anywhere.
