How is Saybolt viscometer used?
A device used to measure the viscosity of a fluid. The saybolt viscometer controls the heat of the fluid and the viscosity is the time is takes the fluid to fill a 60cc container. The device used for measurement of viscosity is known as viscometer .
What is Saybolt Furol viscosity?
Saybolt Furol viscosity – the efflux time in seconds required for 60 milliliters of a petroleum product to flow through the calibrated orifice of a Saybolt Purol viscometer, under carefully controlled temperature, as prescribed by test method ASTM D 88.
What is the difference between Redwood viscometer and Saybolt viscometer?
Answer: A Redwood viscometer works on the same principle of Saybolt viscometer. Here, the stopper is replaced with an orifice and Redwood seconds is defined for collection of 50ml of liquid to flow out of orifice. In general, both the viscometers are used to compare the viscosities of different liquid.
How is viscosity of bitumen measured?
The viscosity of liquid bitumen is measured by efflux visconnectors. The Saybolt Universal Second (S.U.S) is a measure of kinematic viscosity. It is the time required for 60 ml of oil to flow through a calibrated tube at a controlled temperature. It is used when the oils have flow time upto 5600 seconds.
What is the importance of Saybolt viscosity test?
Saybolt Furol viscosity test is used to determine viscosity of liquid bitumens. In this test, time in seconds is noted for 60 ml of the liquid bitumen at specified temperature to flow through an orifice of a specific size. The higher the viscosity of the bitumen more time will be required for a quantity to flow out.
Is code for Saybolt viscometer?
This test method describes how to find out the viscosity of bitumen emulsion with Saybolt Furol viscometer. It is applicable to all the emulsified asphalts specified in Specifications IS-3117-2004.
What is Redwood viscosity?
‘Redwood Viscometer’ determines the viscosity in terms of seconds (which are terms as Redwood seconds), a time taken by oil to pass through a standard orifice, and collection of the same oil in 50 cc flask. Originally Redwood Viscometer was developed for the measurement of viscosity of petroleum products.
What is viscosity of asphalt?
Asphalt binder viscosity measures a fluid’s resistance to flow and is typically measured to replicate the HMA pavement surface temperature during summer in the USA (60°C or 140°F). Liquid resistance in flowing is viscosity by definition.
How do you test bitumen?
Tests on bitumen
- Penetration test.
- Ductility test.
- Softening point test.
- Specific gravity test.
- Viscosity test.
- Flash and Fire point test.
- Float test.
- Water content test.
What is Saybolt number?
Specifically that the saybolt color chart is used as an indication of the overall purity of kerosene and can identify if improper storage or handling of the fuel has occurred. The measurement of the color of petroleum products is also defined by ASTM D1500.
What is viscosity test?
Viscosity is often referred to as the thickness of a fluid, where water has a low viscosity and honey has a high viscosity. This technique is good for Newtonian fluids and can be used to determine the intrinsic or inherent viscosity of a material. …
How do you measure viscosity of emulsion?
Higher the viscosity, lower the rate of flow. The test is conducted to see if it is in the specified range. The Test result is expressed in seconds for the flow of 60 cc of the emulsion sample through a 3.8 mm diameter orifice under the specified conditions of the test.
How are the results of Saybolt universal viscosity measured?
The test results are specified in seconds (s), more often than not referencing the test: Saybolt universal seconds (SUS); seconds, Saybolt universal (SSU); seconds, Saybolt universal viscosity (SSUV); and Saybolt FUROL seconds (SFS); seconds, Saybolt FUROL (SSF). The precise temperature at which the test is performed is often specified as well.
What are the different types of Saybolt viscometers?
The saybolt viscometer, one of the efflux cup viscometers is the standard instrument for testing petroleum products. There are three types of orifices available-Universal, Furol, Asphalt. The furol and asphalt orifices, respectively, have an efflux time of approximately, one-tenth and one-hundredth that of the universal orifice.
Which is the test method for Saybolt FUROL?
5.4 Determination of the Saybolt Furol viscosity of bituminous materials at higher temperatures is covered by Test Method E102/E102M. 1. Scope 1.1 This test method covers the empirical procedures for determining the Saybolt Universal or Saybolt Furol viscosities of petroleum products at specified temperatures between 21 and 99°C [70 and 210°F].
How big is the Saybolt universal orifice viscometer?
Of these types, the universal orifice(saybolt universal viscometer) is most commonly used and its efflux time is designated as saybolt universal seconds(SUS).The universal viscometer measures the time required for 60 cc of sample fluid to flow out through an orifice having dimensions of 0.176 cm in diameter and 1.225 cm in length.
