What is SSU viscosity unit?

What is SSU viscosity unit?

SSU viscosity means the number of seconds it takes 60 cubic centimeters of an oil to flow through the standard orifice of a Saybolt Universal viscometer at 100 degrees Fahrenheit.

What is SSU Saybolt seconds universal?

Saybolt Universal Second (Often SUS or SSU) is a measure of kinematic viscosity used in classical mechanics . It is the time that 60 cm3 of oil takes to flow through a calibrated tube at a controlled temperature.

Is SSU for kinematic or dynamic viscosity?

Measuring Saybolt Seconds Universal (SSU) In the United States, kinematic viscosity is often described as Saybolt viscosity, expressed as Saybolt Universal Seconds (SUS) or Saybolt Seconds Universal (SSU).

Is SSU the same as SUS?

Viscosity—Because an oil’s viscosity changes with temperature, it is always expressed at a reference temperature, usually 100° and 210° F. The most common unit in the United States is the Sabolt Universal Seconds (SUS) or Sabolt Seconds Universal (SSU), which is measured with a Saybolt Viscosimeter.

What is the viscosity of water in SSU?

What is Saybolt viscometer used for?

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.

What does SSU mean for oil?

Sabolt Seconds Universal
The most common unit in the United States is the Sabolt Universal Seconds (SUS) or Sabolt Seconds Universal (SSU), which is measured with a Saybolt Viscosimeter. The tested oil is brought to 100° F and poured through a standard orifice of 0.0695 in. in diameter.

What does mm2 s mean?

square millimetre per second
The SI unit of kinematic viscosity is the square metre per second, m2/s. The normal sub- unit derived from this is the square millimetre per second, mm2/s = 10-6 m2/s.

What is sus oil?

Saybolt Universal Seconds (SUS), which is the time in seconds for 60 milliliters of oil to flow through a standard orifice at a given temperature. This viscosity system is still in limited use, although it has been generally replaced by the ISO grading system. « Back to Glossary Index.

What does sus mean for hydraulic oil?

Hydraulic oils thickness is specified by a SUS or SSU designation, similar to the SAE designation used for automotive fluids. SUS stands for Saybolt Universal Seconds (or as some put it, Saybolt Seconds Universal). It is a measuring system set up by a man named Saybolt.
