What is the density of water?
Density is the mass per unit volume of a substance. The density of water is most given as 1 g/cm3, but below is the density of water with different units. It's no coincidence that water has a density of 1. Density is mass divided by volume (ρ=m/v), and water was used as the basis for establishing the metric unit of mass, ...
How to find the density of a liquid?
Calculating the Density of a Liquid With a Hydrometer. If you're trying to calculate the density of a liquid, you also can do so by using an instrument known as a hydrometer. A hydrometer looks like a thermometer with a large bulb at one end to make it float.
How to measure density of a substance?
In order to measure the density of a substance, you can calculate a regularly-shaped object's volume and proceed from there, measure the volume of a liquid or how much liquid an irregular object displaces in a graduated cylinder, or use a hydrometer to measure the density of a liquid.
How to find the volume of an object?
If the object has an irregular shape and you can't easily calculate its volume, you can find its volume by placing it in a graduated cylinder filled with water and measuring the volume of water it displaces. Archimedes' Principle states that an object displaces a volume of liquid equal to its own volume.
Why does ice float on top of water?
Once you get below water's freezing point (3 2°F/0°C), the density of water decreases because ice is less dense than water. This is why ice floats on top of water and, when you put ice cubes in a glass of water, they don't just sink straight to the bottom. The chart also shows that, for the range of temperatures typical for indoor science labs ...
Does water change density?
Water's density changes depending on the temperature, so if you're doing an experiment close to or past water's boiling or freezing point, you'll need to use a different value to take into account the change in density. Both steam and ice are less dense than water.
Is salt water higher than sea water?
Saltwater (like the oceans) has a different density which depends on how much salt is dissolved in the water. Seawater density is typically slightly higher than the density of pure water, about 1.02g/cm 3 to 1.03g/cm 3.
How does this water density calculator work?
This is a tool that helps you determine water density in kg/m 3 in two different situations. The first is based only on temperature values and in this case you only need to input temperature in Celsius, Fahrenheit, Kelvin or Rankine.
Example calculation
Let’s take for example a sample of water at a temperature of 15 degrees Celsius with a salinity of 3000 mg/L.
Water facts
Density of pure water is a constant at a certain temperature not depending on sample.
What is the density of water?
Water differs from most liquids in that it becomes less dense as it freezes. It has a maximum of density at 3.98 °C (1000 kg/m 3 ), whereas the density of ice is 917 kg/m 3. It differs by about 9% and therefore ice floats on liquid water.
What is the temperature of the water in a reactor?
Inlet temperature of the water is about 290°C (⍴ ~ 720 kg/m 3 ). The water (coolant) is heated in the reactor core to approximately 325°C (⍴ ~ 654 kg/m 3) as the water flows through the core.
How does heavy water differ from most liquids?
Also heavy water differs from most liquids in that it becomes less dense as it freezes. It has a maximum of density at 3.98 °C (1110 kg/m 3 ), whereas the density of its solid form ice is 1017 kg/m 3.
How does density change?
It has units of cubic meter per kilogram (m 3 /kg). Changes of Density. In general, density can be changed by changing either the pressure or the temperature. Increasing the pressure always increases the density of a material. The effect of pressure on the densities of liquids and solids is very very small.
Where does coolant flow in a reactor?
Inside the reactor pressure vessel (RPV), the coolant first flows down outside the reactor core (through the downcomer). From the bottom of the pressure vessel, the flow is reversed up through the core, where the coolant temperature increases as it passes through the fuel rods and the assemblies formed by them.
Why are water and steam considered a medium?
Water and steam are a common medium because their properties are very well known. Their properties are tabulated in so called “Steam Tables”. In these tables the basic and key properties, such as pressure, temperature, enthalpy, density and specific heat, are tabulated along the vapor-liquid saturation curve as a function of both temperature and pressure.
Does temperature affect the densities of liquids and solids?
The effect of temperature on the densities of liquids and solids is also very important. Most substances expand when heated and contract when cooled. However, the amount of expansion or contraction varies, depending on the material. This phenomenon is known as thermal expansion.

What is the measure of a fluid's resistance to flow?
Viscosity is the measure of a fluid's resistance to flow. The higher the viscosity of a fluid is, the slower it flows over a surface. For example, maple syrup and honey are liquids with high viscosities as they flow slowly. In comparison, liquids like water and alcohol have low viscosities as they flow very freely.
What is the best fluid to learn about viscosity?
Water, being the most studied liquid, is the best fluid to start with when learning about viscosity. The dynamic viscosity of water at room temperature has a value of around 1.0 mPa⋅s, and it decreases as temperature increases. This value is the viscosity of water at 20°C.
What is the difference between dynamic and kinematic viscosity?
When choosing between the two viscosities, it is worth noting that dynamic viscosity tells us about the force required to move the fluid at a certain speed. On the other hand, the kinematic viscosity tells about the speed the fluid reaches when a particular force is applied to the fluid.
How does sugar affect water viscosity?
Adding substances that make water thick , like sugar, increases the viscosity of water. The more sugar is added, the more viscous the water gets and the thicker it becomes. Adding heat to the mixture will help in mixing more sugar into the water.
How to make water flow slower?
Put the water at a very low temperature to increase its viscosity. At lower temperatures, water molecules tend to lose energy, making them pile up each other closely. This piling up results in the water molecules experiencing more friction against each other, making them flow slower or become viscous.
Why do liquids have a lower viscosity?
In liquids, when molecules start to move faster, their attraction from each other weakens. This weakening results in liquid molecules to move more freely and , therefore, with a lower viscosity.
Does water have a higher viscosity?
Water tends to have higher viscosity at lower temperatures and a lower viscosity at higher temperatures. Think of placing water in a freezer. The water molecules at a lower temperature start to lose their energy, get attracted to each other more, and flows rather slowly until the water turns to ice.
