How do you calculate specific gravity of a gas?
Gas specific gravity is defined as the ratio of the density of the gas to the density of air at 1 atm pressure at 60°F (standard conditions). If ideal gas law behavior is assumed, gas specific gravity is the molecular weight of the gas divided by the molecular weight of air.
How many grams are in specific gravity?
Specific gravity is a ratio of the density of a substance to the density of a reference substance, usually water. Since the density of water is one gram per cubic centimeter, you calculate specific gravity by dividing the density of a substance by one gram per cubic centimeter.
How do you calculate gas factor?
Gas formation volume factor is defined as the ratio of gas volume at reservoir condition to the gas volume at standard condition, that is,(2.62)Bg=VVsc=pscpTTsczzsc=0.0283zTp,where the unit of formation volume factor is ft3/scf.
What is the specific weight of gasoline?
Specific gravity is simply the ratio of the specific weight of a given liquid to the specific weight of water at 4° C (γwater = 9.81 kN/m3 or 62.4 lb/ft3)….©Kurt Gramoll.
| 20°C (68°F) 1 atm | Density, ρ | |
|---|---|---|
| Carbon Tetrachloride | 1,590 | 3.085 |
| Ethanol | 789 | 1.531 |
| Freon 12, liquid | 1,327 | 2.575 |
| Gasoline | 680 | 1.319 |
What is gas conversion factor?
The conversion factor equals the average MJ of gas (that is the amount of energy used) to heat each decalitre of hot water used in your building for the billing period. • Each unit’s hot water meter records the amount of hot water used.
How do you calculate specific gravity from specific weight?
For example, the specific gravity of 0.84 corresponds to the density of 840 (0.84 x 1000) kg/cubic meters. Multiply the density by the acceleration of gravity (9.81) to calculate the specific weight. In our example, the specific weight is 840 x 9.81 = 8,240.4.
Is specific gravity same as specific weight?
Specific gravity is a dimensionless quantity whereas specific weight has dimensions. The specific gravity of a material is independent of the gravitational field, but the specific weight of a material is dependent on the gravitational field.
How do I calculate specific weight?
Multiply the density by the acceleration of gravity (9.81) to calculate the specific weight. In our example, the specific weight is 840 x 9.81 = 8,240.4.
