What equipment uses specific gravity?

A hydrometer is an instrument used to determine specific gravity. It operates based on the Archimedes principle that a solid body displaces its own weight within a liquid in which it floats.

Which machine is preferred for specific gravity test?

Specific Gravity Bench is the best solution for weighing suspended samples in water for specific gravity measurements of aggregates, hardened concrete, bituminous mixtures, and many other materials. Specific Gravity Water Tanks have a 30gal or 44gal capacity and are equipped with drain and overflow outlets.

What is specific gravity apparatus?

Specific Gravity (Density) apparatus, BS: 1881-114./Buoyancy Balance. Consists of a rigid support frame, incorporating a water tank mounted on a platform. A mechanical lifting device is used to raise the water tank through the frame height immersing the specimen suspended below the balance.

What is specific gravity in construction materials?

Specific gravity is defined as the ratio of the density of the solid part of a material to the density of water at 20°C.

How do you measure specific gravity in a lab?

The specific gravity, then, may be determined by dividing the weight of a substance in grams by its volume in c.c.; but it is more convenient in practice to determine it by dividing the weight of the substance by the weight of an equal volume of water.

Which sieve is used in the specific gravity test of CA?

This test method describes the procedure for the determination of the specific gravity of soils by means of a pycnometer. This method is only used for the testing of soil particles passing the No. 4 sieve. When the soil contains particles retained on the No.

What is Lactometer used for?

A Milk Hydrometer also known as a lactometer is an instrument that is used to check for the purity of milk by measuring its density. Milk of given fat % content can have density within a certain fixed range. A lactometer consists of a cylindrical graduated tube closed at both ends.

What is Baume light hydrometer?

In hydrometer. The Baumé hydrometer, named for the French chemist Antoine Baumé, is calibrated to measure specific gravity on evenly spaced scales; one scale is for liquids heavier than water, and the other is for liquids lighter than water.

Which machine is preferred for abrasion test?

Which machine is preferred for abrasion test? Explanation: Los Angeles is preffered for abrasion test for carrying out the hardness property and has been standardized in India.

What is specific gravity of cement?

Limit: Specific gravity of cement = 3.15 g/cc.

What is specific gravity used for?

The term “Specific Gravity” (SG) is used to define the weight or density of a liquid as compared to the density of an equal volume of water at a specified temperature. The temperature used for measurement is usually 39.2oF (4oC), because this temperature allows water to assume its maximum density.

What instrument measures specific gravity?

A hydrometer is a scientific instrument used to measure both the specific gravity and the density of a liquid, based on Archimedes ’ principle of buoyancy. It is composed of a sealed glass bulb with a long skinny tube connected to one end, and it is weighted with mercury or lead shot under the bulb so it can float upright.

What is an example of specific gravity?

1 slug = 32.174 lb m = 14.594 kg

  • 1 kg = 2.2046 lb m = 6.8521×10 -2 slugs
  • density of water: 1000 kg/m 3,1.938 slugs/ft 3

    • What is the engineering significance of specific gravity?

    Specific gravity is an important property of cement being related to its density and viscosity. It is one of the factor to determine density of cement. If the specific gravity of cement is more than 3.19 then it has more moisture content, which will affect the mix and bonding.

    How do you calculate the specific gravity of a solution?

    Here is the formula for calculating specific gravity: SG = (ρ object or liquid)/ ρ water. The formula could be rewritten if you already have the specific gravity of a solid object or liquid and what you need to calculate is their density. In which case, the formula would be the following: SG x ρ water = ρ object or liquid.
