What instrument is used to measure specific gravity?
hydrometer
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. Hydrometers can be divided into two general classes: liquids heavier than water and liquids lighter than water.
What is the name of apparatus used for specific gravity test?
Vacuum Pycnometers are available in three diverse options for specific gravity determinations including 2,000g and 6,000g Pycnometers, as well as Heavy-Wall Glass Filter Flasks. Flasks are available for the specific gravity testing of cement, soils, aggregate, bitumen, pitch, and other materials.
What is specific gravity used for?
Significance and Use 4.1 Specific gravity is an important property of fluids being related to density and viscosity. Knowing the specific gravity will allow determination of a fluid’s characteristics compared to a standard, usually water, at a specified temperature.
What is the use of specific gravity of coarse aggregate?
Overview. The coarse aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a coarse aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is similar in nature to the fine aggregate specific gravity test.
How specific gravity is measured?
Specific Gravity, on the other hand, is defined as the weight of a sample, at a given temperature, divided by the weight of the same volume of water, at the same temperature or a different specified temperature. Specific Gravity of liquids is most conveniently measured using a Hydrometer.
What instrument measures humidity?
hygrometer
The instrument used to measure relative humidity is the hygrometer. A variety of different digital and analog models exist, but you can build a simple version with your class. Known as the sling psychrometer, this hygrometer takes a measurement with a “wet bulb” thermometer and a “dry bulb” thermometer simultaneously.
Why specific gravity test is done?
A urine specific gravity test compares the density of urine to the density of water. This quick test can help determine how well your kidneys are diluting your urine. Urine that’s too concentrated could mean that your kidneys aren’t functioning properly or that you aren’t drinking enough water.
What are the factors affecting specific gravity test?
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.
How do you explain specific gravity?
The specific gravity of an object is the ratio between the density of an object to a reference liquid. The specific gravity has no units. If the specific gravity has a value of greater than one, then the object sinks in water and if it is less than one, then the object floats in water.
Is density specific gravity?
Density is defined as mass per unit volume. 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.
Why do we test specific gravity?
A urine specific gravity test compares the density of urine with the density of water. It allows doctors to see the concentration of all particles that are present in the urine. The test involves collecting a urine sample that will help give a doctor an idea of a person’s kidney function and hydration status.
How is specific gravity measure?
How does the Google specific gravity apparatus work?
The apparatus provides an overflow feature wherein the test liquid which is dropped down a fluid column for specific gravity determination subsequently flows up a second column to a drain. This feature enables the initial fluid column to be conveniently repetitively used for specific gravity determinations.
How is the specific gravity of a liquid determined?
Apparatus useful in the determination of specific gravity of a test liquid by the falling-drop method is described. The apparatus provides an overflow feature wherein the test liquid which is dropped down a fluid column for specific gravity determination subsequently flows up a second column to a drain.
What kind of equipment is used for specific gravity testing?
Flasks are available for the specific gravity testing of cement, soils, aggregate, bitumen, pitch, and other materials. Vacuum Pumps range from small to heavy-duty models for specific gravity tests.
Which is the correct definition of apparent specific gravity?
Apparent Specific Gravity:The ratio of the weight in air of a unit volume of the impermeable portion of aggregate (does not include the permeable pores in aggregate) to the weight in air of an equal volume of gas-free distilled water at the stated temperature.
