The pressures are stated in mega-Pascals, where a Pascal is a Newton per square meter, and as a multiple of standard atmospheric pressure. ĭensity of crude oil, Density of fuel oils, Density of lubricating oil and Density of jet fuel as function of temperature.Īs shown in the figures, the change in density is not linear with temperature - this means that the volumetric expansion coefficient for water is not constant over the temperature range.Water Vapor and Vapor Pressure Saturated Vapor Pressure, Density for Water Tempīelow are some selected values of temperature and the saturated vapor pressures required to place the boiling point at those temperatures. įor other substances, see density and specific weight of acetone, air, ammonia, argon, benzene, butane, carbon dioxide, carbon monoxide, ethane, ethanol, ethylene, helium, hydrogen, methane, methanol, nitrogen, oxygen, pentane, propane and toluene.

See Water and Heavy Water for thermodynamic properties at standard condtions. The density of water depends on temperature and pressure as shown below: And by the way, so what is this unit here This. A relationship between density and salinity was determined in a salinity range between 2 g kg 1 and 35 g kg 1 and at temperatures between 5 C and 35 C. The second calculation made by the water density calculator discovers density taking into account both. The first is based only on temperature values and in this case you only need to input temperature in Celsius, Fahrenheit, Kelvin or Rankine. And then these lines are lines of constant seawater density. This is a tool that helps you determine water density in kg/m 3 in two different situations. Note! Temperature must be within the ranges 0-370 ☌, 32-700 ☏, 273-645 K and 492-1160 °R to get valid values. On this axis is temperature in degrees Celsius. The output density is given as g/cm 3, kg/m 3, lb/ft 3, lb/gal(US liq) and sl/ft 3. The calculator below can be used to calculate the liquid water density at given temperatures. See more about the difference between mass and weight Online Water density Calculator Γ = 1.940 * 32.174 = 1.940 /(*) * 32.174 = 62.4 A 10.5 ml sample of water at 23.5 o C, delivered from a pipet had a mass of 10.4532 grams as measured on an analytical balance. The density of water is 1.940 sl/ft 3at 39 ☏ (4 ☌), and the specific weight in Imperial units is Example: to find the density of water at 16.1 ☌, you would first find the whole degree by searching down the left hand column until you reach 16. And its vapor pressure is 23.8 millimeters of mercury. Will all of the water evaporate at 25 degrees Celsius And then they tell us at 25 degrees Celsius, the density of water is 0.997 grams per milliliter. You seal the room and wait for the water to evaporate. It is exactly 1000 kg/m3 at 4 degrees Celsius. But you’re right that it does vary a little bit with temperature. In the Imperial system the mass unit is the slug, and is derived from the pound-force by defining it as the mass that will accelerate at 1 foot per square second when a 1 pound-force acts upon it :ġ = 1 * 1 and 1 = 1 /1 The room has a volume of 4.25 times 10 to the fourth liters. In general, we say that the density of water is 1000 kg/m3 (or 1 g/cm3). Get the free 'Water Density Calculator' widget for your website, blog, Wordpress, Blogger, or iGoogle. In the SI system, specific weight of water at 4☌ will be: This widget calculates the density of water at various temperatures and pressures. G = acceleration due to gravity, units typically and value on Earth usually given as 9.80665 m/s 2or 32.17405 ft/s 2 Specific weight is the ratio of the weight to the volume of a substance: The specific volume of water depends on temperature as shown below: Heavy. The output specific volume is given as cm /g, ft /lb, gal (US liq)/lb and ft. Pure water has its highest density 1000 kg/m 3 or 1.940 slug/ft 3 at temperature 4☌ (=39.2☏). The calculator below can be used to calculate the liquid water specific volume at given temperatures. Density is the ratio of the mass to the volume of a substance:
