State (this is 3% more than the below tabulated value of density at 125☏ and 725 psia.) Note! For pressure between 20 and 100 bara, the error may be up to 7% by using this approximation (higher error, the higher pressure).Įxample 1: Density of hydrogen at 5 bara and 24 ☌.Ĭalculator gives the density at 24 ☌ and 1 bara: 0.0815 ĭensity at 24☌ and 5 bara: 0.0815 * 5/1 = 0.408 Įxample 2: Density of hydrogen at 725 psia and 125 ☏.Ĭalculator gives the density at 125 ☏ and 14.5 psia: 0.00465 ĭensity at 125☏ and 725 psia: 0.00465 * 725/14.5 = 0.233
If pressure is given in psia, you have to multiply the density at 14.5 psia with the actual higher pressure (in psia) and divide by 14.5. Temperature Choose the actual unit of temperature: ☌ ☏ K °Rįor calculation of density at higher pressure (up to 100 bara / 1450 psia), a good approximation is to multiply the density at 1 bara with the actual, higher pressure (in bara). Specific weight is given as N/m 3 and lb f/ ft 3. The output density is given as kg/m 3, lb/ft 3, lb/gal(US liq) and sl/ft 3. The calculator below can be used to estimate the density and specific weight of gaseous hydrogen at given temperature and atmospheric pressure (1 bara/14.5psia). Tabulated values of hydrogen density at given temperature and pressure (SI and Imperial units) as well as density units conversion are given below the figures. Where g = acceleration due to gravity, units typically and value on Earth usually given as 9.80665 or 32.17405 Specific weight, γ, has units typically or is defined by the ratio of the weight to the volume of a substance: Density, ρ, has units typically or, and is defined by the ratio of the mass to the volume of a substance:
