Density is usually calculated using a standard equation. If you wanted to measure the density of ocean water but did not have the expensive equipment to do it directly, you would have to collect a sample of sea water and bring it back to a controlled environment to be measured.

The density of ocean water is rarely measured directly. The output density is given as g/cm 3, kg/m 3, lb/ft 3, lb/gal(US liq) and sl/ft 3. Density is a measure of the amount of mass contained in a unit of volume.The general trend is that most gases are less dense than liquids, which are in turn less dense than solids, but there are numerous exceptions. The calculator below can be used to calculate the liquid water density at given temperatures. Hence, ocean water moves laterally along the layers with the same density. Heres a table of densities of common substances, including several gases, liquids, and solids. That surface level movement is to some degree vertical and horizontal, perhaps swirling, but within the same general density layer. Circulation in the depths of the ocean is horizontal, a result of deviations in density in constrast to surface circulation which is a product of surface winds. The deep ocean is layered with the most dense water on bottom and the lightest water on top. So, the density of ocean water increases somewhat proportionately as you go to or toward the bottom of the ocean. The temperature of the ocean decreases significantly as you go to the bottom of the ocean. Hence, a layer of water (pycnocline) with higher salinity can actual float on top of water with lower salinity if the layer with higher salinity is quite a bit warmer than the lower salinity layer. However, temperature has a greater effect on the density of water than does salinity. Thermal diffusivity For each topic, there are figures and tables showing the variations in properties with temperature. At atmospheric pressure (0 bar g, absolute 1 bar ) water boils at 100 o C and 417. Example - Boiling Water at 100 o C, 0 bar (100 kPa) Atmospheric Pressure. Given two layers of water with the same salinity, the warmer water will float on top of the colder water. 1) 1 bar abs 0 bar gauge 100 kPa abs atmospheric pressure Vacuum steam is the general term used for saturated steam at temperatures below 100☌. Less dense water floats on top of more dense water. Increasing salinity also increases the density of sea water. So, the colder the water, the more dense it is. Ocean water gets more dense as temperature goes down. The first is the temperature of the water and the other us the salinity of the water. There are two main factors that make ocean water more or less dense than about 1027 kg/m 3. Density of ocean water at the sea surface is about 1027 kg/m 3. Ocean water is more dense because of the salt in it. The density of pure water is 1000 kg/m 3. Freezing water expands over 9 by volume and ice floats on water because it is lighter. At 4 degrees Celsius pure water has a density of 1g/mL or 1kg/L and a specific gravity of 1. The density of water varies according to temperature and the degree of purity. The density of water increases with decreasing temperature, reaching a maximum at 4.0 ☌, and then decreases as the temperature falls below 4.0 ☌.

Table 14.2 shows the density of water in various phases and temperature. This is applicable for any fluid that is primarily water based. Density of pure water is a constant at a certain temperature not depending on sample. The density of solids and liquids normally increase with decreasing temperature. Then click on the Calculate button and the water density is calculated and displayed, based on your input data. In our calculator, enter the temperature in degrees C or F (click anywhere outside of any of the fields for the conversion), and the salinity in mg/L or the equivalent of PPM. Use this calculator to account for pressure. Pressure is a large factor in water density in the ocean.

This script determines the density of water is a function of both temperature and salinity pressure is assumed at the surface since this is for non-depth related samples. This calculator requires the use of Javascript enabled and capable browsers.
