What is specific gravity for water?

4.6. The specific gravity of a liquid is the relative weight of that liquid compared to an equal volume of water. The specific gravity of water is de facto 1.

How do you calculate the specific gravity of water?

Calculate the object’s specific gravity by dividing its density by the density of water at 4 degrees Celsius. It follows that pure water has a specific gravity of 1 or close to 1 depending on temperature.

What is specific gravity in fluid mechanics?

The specific gravity of a fluid, designated as SG, is defined as the ratio of the density of the fluid to the density of water at some specified temperature. Usually the specified temperature is taken as 4 °C and at this temperature the. density of water is 1000 kg/m3.

What is the specific weight of water?

A commonly used value is the specific weight of water on Earth at 4 °C (39 °F), which is 9.807 kilonewtons per cubic metre or 62.43 pounds-force per cubic foot.

What is the specific gravity of water at 4 Celsius?

1.000
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.

Is specific gravity g mL?

Specific gravity is the ratio of density of a substance compared to the density of fresh water at 4°C (39° F). At this temperature the density of water is at its greatest value and equal 1 g/mL. Since specific gravity is a ratio, so it has no units.

How is SG calculated?

As per the specific gravity definition, the value is calculated as the density of that substance divided by water density at 4⁰C. To obtain the specific weight of a substance, its specific gravity is multiplied by 1000 (density of water in kg/m³).

How do I calculate specific gravity?

The formula for specific gravity, given that the reference substance is water, is the density of the object divided by the density of the water.

What is specific gravity of water at 80 C?

0.9735

Is density same as specific gravity?

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 an example of specific gravity?

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 specific gravity of heavy water?

Specific gravity of liquid water ranging 32 – 700 o F and 0 – 370 o C is given in figures and tables below: See Water and Heavy Water – thermodynamic properties.

How to calculate density, specific weight and specific gravity?

Which is a dimensionless unit of specific gravity?

Specific Gravity (= Relative Density) – SG – is a dimensionless unit defined as the ratio of the density of a substance to the density of a reference substance – at a specified temperature and pressure, and can be expressed as.

What is the specific weight of water at 4°C?

In the SI system, specific weight of water at 4°C will be: γ = 1000 [kg/m3] * 9.807 [m/s2] = 9807 [kg/ (m2 s2)] = 9807
