Gas properties Specific gravity (relative density) The specific gravity of a gas, γ, is the ratio of the density of the gas at standard pressure and temperature to the density of air at the same standard pressure and temperature. The standard temperature is usually 60°F, and the standard pressure is usually 14.696 psia.

- This calculator converts percentage by weight or parts by weight to percentage by volume and also parts by volume. The Density or Specific Gravity of each indivdual component is required. This calculator is useful when mixing components by volume is preferred to mixing by weight. Density can be in any units provided the units are the same for all components. Specific Gravity is unitless so it can be used anytime. Please do not use a mix of density and Specific Gravity. Please use the Add Rows button if there are more than two components.

Q & A: What is specific gravity? If it is less dense than water, then the specific gravity is less than 1. To calculate the specific gravity of a liquid, you have to know its density. Take the density of the liquid, divided by the density of water (1 gm/cm3), and you will get the specific gravity of the liquid: Sp.G. = (density of liquid) / (1 gm/cm3)

- Specific Gravity. Specific gravity is defined in Webster's dictionary as the ratio of the weight or mass of a given volume of a substance to that of another substance (usually water for solids and liquids) used as a standard. Specific gravity is not expressed in units as it is purely a ratio. Density Table.

Specific gravity Being a ratio of densities, specific gravity is a dimensionless quantity. Specific gravity varies with temperature and pressure; reference and sample must be compared at the same temperature and pressure or be corrected to a standard reference temperature and pressure. Substances with a specific gravity of 1 are neutrally buoyant in water.

- Let's go over those steps for using the Ideal Gas Law to calculate the molar mass of the gas: 1) You have to know the grams of gas involved. Usually the problem will just give you the value, but not always. You might have to calculate it. 2) You are going to have to calculate the moles of gas. Use PV = nRT and solve for n.

How to calculate the amount of gas in a compressed cylinder How to calculate the amount of gas in a compressed cylinder. Turns out my assumptions were wrong about the stated 9450 L of N2 gas. The 9450 L is the total volume of standard pressure gas compressed into the cylinder to 20 MPa. Using V2=V1/(P2/P1) having P1=0.101 MPa, P2=20 MPa, V1=9450 L. The total volume of gas within the cylinder is about 47 L a reasonably fitting size for the cylinder dimensions.

HYDRAULIC FLUIDS:Density and Specific Gravity If the specific gravity of a liquid or solid is known, the density can be obtained by multiplying its specific gravity by the density of water. For example, if a hydraulic fluid has a specific gravity of 0.8, 1 cubic foot of the fluid weighs 0.8 times the weight of water (62.4 pounds) or 49.92 pounds. Specific gravity and density are independent of the size of the sample and depend only on the substance of which it is made. Viscosity.

- Specific Gravity of Propane Gas - One cubic foot of propane weighs .1162 lbs. and one cubic foot of air weighs .07655. Dividing .1162 by .07655 equals 1.52. What does this mean? Propane is heavier than air and will seek the lowest space available. Specific Gravity of Liquid Propane - One gallon of propane weighs 4.24 lbs. One gallon of water weighs 8.33 lbs. Dividing 4.24 by 8.33 equals .51. This means propane is less dense than water (lighter than water) and will not sink in water, so to speak.

- Only if the specific gravity of the liquid is very low or very high will the flow change by more than 10 percent from that of water. The effect of specific gravity on gases is similar. For example, the specific gravity of hydrogen is 93 percent lower than that of air, but it changes flow by just 74 percent. Carbon dioxide has a specific gravity 53 percent higher than that of air, yet it changes flow by only 24 percent.
