Something about the density of water

Maximum density of water, and its conditions

The density of water, as other values which are not constant, has its own maximum. This point is described for water which meets 2 conditions. What are these conditions? 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 conditions. But 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 here is also an approximate result: 62.4 lb/ft3.

Does salt increase the density of water?

Do you know that the density of water changes depending on its salinity? Simply put, freshwater, like water which you drink daily, will have a different density than the saltwater, like water in the sea. To make this issue clearer, the bigger density will have seawater, not freshwater. What is the exact value of seawater in lb/ft3? Let’s see: the density of seawater is equal to 63.9262 lb/ft3. Do you know that this density is about 1.5 lb/ft3 bigger than the density of freshwater which is equal to 62.4264 lb/ft3?

How can you calclualte density of water?

How to calculate the density of water? The key to understanding the process is to focus on the definition of density. As simply as possible, the density is just the mass of water divided by the volume of water. So based on it, to calculate the density of water, you should divide the value of the mass by the value of the volume. That’s all, then you will get your result. You probably know it, but to make it clear – if you want to get the result in lb/ft3 you need to calculate the mass in pounds and volume in cubic feet. Remember – if the numbers will be difficult to calculate on your own, you can always use a calculator.

How does the density of water lb/ft3 look? To answer this question you first need to see the definition of the density of water at all. So how does it look? It is nothing but the mass of a water per unit volume of water. So to sum up, it is kind of a descriptive definition. The legal one has not been established. But let’s focus on the density of water lb/ft3. Based on the general definition of density of water, the density of water lb/ft3 is the mass determined in pounds per volume determined in cubic feet.

The value of the density of water lb/ft3 depends on a few conditions, like the temperature or the salinity, but there is also the basic value. How does it look? 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? Regardless of whether your type was close to the answer or not, one thing is obvious. If you have learned the basic value, you will learn easily also about other values of water density when the specific factors will act on it.

Density of water value

The density of water lb/ft3 has not a constant value. In other words, it changes when even one of the conditions changes. What about these conditions which affects water density? There are 2 main conditions – the temperature of the water and the salinity of the water. To make it clear, when the temperature changes, the water density lb/ft3 takes different values. The same applies to salinity. Saltwater and freshwater have different values of density. And when these 2 conditions change together, the change of water density is more significant.
