What is the value of specific gravity of water and mercury?
Example – density. The specific weight of water at ordinary temperature and pressure is 9.81 kN/m3. The specific gravity of mercury is 13.56. Compute the density of water and the specific weight and density of mercury.
What is specific of mercury?
The specific gravity of mercury is 13.6.
What is the specific gravity water?
In less dense liquids the hydrometer will float lower, while in more dense liquids it will float higher. Since water is the “standard” by which other liquids are measured, the mark for water is probably labeled as “1.000”; hence, the specific gravity of water at about 4°C is 1.000.
What is the specific gravity of mercury if it has a density of 13.6 g mL?
| Substance | Density (g/mL) |
|---|---|
| Water | 1.00 |
| Gold | 19.3 |
| Mercury | 13.6 |
What is the specific gravity of water at 25 C?
0.99707
| Temperature | Pressure | SG at reference temperature |
|---|---|---|
| 10 | 1 atm 14.7 psi 101.3 kPa | 0.99973 |
| 15 | 0.99913 | |
| 20 | 0.99823 | |
| 25 | 0.99707 |
What is specific gravity of water?
to 1
Water has a specific gravity equal to 1. Materials with a specific gravity less than 1 are less dense than water, and will float on the pure liquid; substances with a specific gravity more than 1 are more dense than water, and will sink.
What does specific gravity equal?
Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. If the relative density is exactly 1 then the densities are equal; that is, equal volumes of the two substances have the same mass.
What is specific gravity vs density?
Density is defined as mass per unit volume. It has the SI unit kg m-3 or kg/m3 and is an absolute quantity. Specific gravity is the ratio of a material’s density with that of water at 4 °C (where it is most dense and is taken to have the value 999.974 kg m-3). It is therefore a relative quantity with no units.
What is the specific gravity of distilled water?
1.000
In the standard hydrometer scale, known as the specific gravity scale, distilled water equals 1.000, the initial point of measurement. Liquids lighter than water are scaled below 1.000 specific gravity, and liquids heavier than water are scaled above 1.000 specific gravity.
How do you find the specific gravity of mercury?
For example, liquid mercury has a density of 13.6 kg per litre; therefore, its specific gravity is 13.6. The gas carbon dioxide, which has a density of 1.976 grams per litre under standard conditions, has a specific gravity of 1.53 (= 1.976/1.29).
What is the equation for specific gravity?
Equations for Specific Gravity. The specific gravity (SG) is a ratio of the density of the substance of interest (ρ i) to the density of the reference substance (ρ r). (Note: The Greek symbol rho, ρ, is commonly used to represent density.) That can be determined using the following formula: SG = ρ i ÷ ρ r = ρ i / ρ r.
What is an example of specific gravity?
1 slug = 32.174 lb m = 14.594 kg
What is the SG of mercury?
Answer and Explanation: The specific gravity of mercury is 13.633. Specific gravity is the ratio of an object’s density to the density of water.
How do you calculate specific gravity of gas?
To find the specific gravity of a gas, you must know its density in kilograms per meter cubed (kg/m 3). Then, divide this density by the density of dry air at standard temperature and pressure.
