The volumetric temperature expansion coefficient, β for water is 0.This pure water density CRM is designed for the calibration of instruments used to. NIST standard pressure is (101.325 kPa or 14.696 psi or 1 atm) UKAS ISO/IEC17025 and ISO Guide 34 certified, density: 0.9982 g/mL at 20 ☌, density: 0.9970 g/mL at 25 ☌.NIST Standard temperature is (20 C or 293.15 K or 68 F).Ice is less dense than liquid water, so it floats. The maximum density of water occurs around 4 degrees Celsius. Note that water can be supercooled and remain a liquid well below its normal freezing point. A standard table lists the values for the density of liquid water. β is the volumetric temperature expansion coefficient, β for water is 0.0002 / C° The density of pure water actually is somewhat less than 1 g/cm 3. ρ is the density of water at a specific temperature.The formula for the density of water based on temperature is: Dry Air and Water Vapor - Density and Specific Volume vs. There are three 'answers' you would get: One molar volume for the liquid phase. Then, press enter until your answer converges. However, this can be automatically converted to compatible units via the pull-down menu. Specific volume, enthalpy and entropy of compressed water. Thus, put the following into your TI calculator to solve for ¯¯ ¯V at 25C, or 298.15 K: (X X3 24.82017175X2 + 5.536X 0.16879264 3X2 49.6403435X +5.536) X. Definitions, online calculator and figures and tables with water properties like density, specific weight and thermal expansion coefficient of liquid water at temperatures ranging 0 to 360☌ (32 to 680☏). The output density is given as kg/m, lb/ft, lb/gal (US liq) and sl/ft. ( β) Volumetric Expansion Coefficient (default: 0.0002 / C° for water)ĭensity of Water (ρ): The calculator returns the density in kilograms per cubic meters. 25: 921: Water, heavy: 11.6: 1105: Water - pure: 4: 1000: Water - sea: 77 o F (25 o C) 1022: Whale oil: 15: 925: Wheatgerm oil: 25: 926. The calculator below can be used to calculate the ammonia gas density and specific weight at given temperatures and atmospheric pressure.INSTRUCTIONS: Choose units and enter the following: Given that the partial molar volume of water in this solution is 16. The Density of Water by Temperature calculator computes the density of water as a function of temperature, using the standard density of water (ρ) at standard temperature and pressure, and the unique temperature expansion coefficient of water. At 25 degrees Celsius, the density of a propanol-water (C3H7OH in H2O) solution which is 30 by mass propanol is 1.05 g/cm3.
