Density of water maximum - main facts about it

Density of water maximum and main facts about it

The density of water, like other non constant values, has its maximum point. The water needs to meet 2 conditions to achieve the maximum point. What are they? It must be freshwater, so the salinity must be lower. The first condition behind us. This freshwater should have the temperature at 4 degrees Celsius too, and that’s all about conditions. So what about the maximum water density value in such conditions? Let’s check: this value is exactly 62.4264 lb/ft3. Due to the fact it is a fraction with many decimals, it may cause some problems with remembering it, so have a look also at a rounded-off result: 62.4 lb/ft3

What is density main factors?

The density of water lb/ft3 is not constant. In other words, value of water density changes when even one of the conditions changes. What about these conditions on which the density of water depends? Focus on 2 main conditions – the temperature of the water and the salinity of the water. It means that when the temperature increases or decreases, the water density lb/ft3 changes the value too. The same applies to salinity. Both salt and fresh water have different values of density. The change is more visible when these 2 conditions change at the same time.

Density and normal boiling point of water

Do you know at which temperature water boils? We are sure you know, but as a reminder – the water boiling point is when its temperature is equal to 100 degrees Celsius. You just have to admit it is a really high number! But the temperature is not the only thing which we want to focus on. We mostly want to show you the value of water density at this temperature. What do you think, how does the density of water lb/ft3 at 100 degrees Celsius look? Have a look at the answer – the water density is equal to 59.8294 lb/ft3 at a boiling point.

Density of water what actually meaning?

How does the density of water lb/ft3 look? To give you the answer, you first have to learn the definition of the water density at all. So how does it look? It is nothing but the mass of a water by unit volume of water. So to sum up, it shows the topic in a descriptive way. The legal one has not been established. But let’s focus on the density of water lb/ft3. Thanks to the general definition we know that the water density lb/ft3 is the mass given in pounds per volume determined in ft3.

Density and the salnity in water

Water density is not a constant value. It changes depending on salinity level, for instance. It means the freshwater, like the water you drink daily, has a different density than the saltwater, like the water in the sea. To be more precise, seawater has a bigger density than freshwater. What is the exact value of seawater in lb/ft3? Here it is: the density of seawater is equal to 63.9262 lb/ft3. So in comparison with the density of freshwater equal to 62.4264 lb/ft3, the density of seawater is about 1.5 lb/ft3 bigger!

Water density at the standard conditions

The value of the density of water lb/ft3 may change depending on a few conditions, like the temperature or the salinity, but there is also the basic value. What is it exactly? The basic value is defined as a value in neutral conditions (freshwater at 4 degrees Celsius) and it is equal to 62.4 lb/ft3. Did you expect such a huge number? Even if you didn’t expect such a value, don’t worry, now it will be easier. If you have learned the basic value, you will learn easily also about other values of density of water in specific conditions.
