How do you convert cSt to sus?

Multiply the cSt value by 4.664 if the test temperature was 210 F. The result is the cSt value converted to SUS. For example: 100 cSt tested at 210 F is equivalent to 466.4 SUS because 100 x 4.664 = 466.4.

What is the unit of cSt?

The SI unit for kinematic viscosity is one meter squared per second and is equivalent to 10,000 St. Usually, centistokes (cSt) is used (1 cSt = 0.01 St = 1 mm2/s). The absolute or dynamic viscosity is equal to the kinematic viscosity, multiplied by the density of the fluid.

How do you convert viscosity from cSt to CP?

Centipoise = centistokes x specific gravity where specific gravity is assumed to be 0.8 (except for water). To find the exact cp of your fluid: cp = cSt x (weight per gallon x 0.120).

Is mm2 s the same as cSt?

mm2/s↔cSt 1 mm2/s = 1 cSt.

Is cSt same as cP?

Although the two terms are regularly interchanged, which is further complicated due to 1 cP being equal to 1 cSt, they are in fact two slightly different terms. cP is the expression for dynamic viscosity, or absolute viscosity of the oil, and is the measure of the fluids resistance to flow.

What is cSt viscosity?

A centistokes (cSt) is a decimal fraction of the CGS unit of kinematic viscosity stokes, which is equal to centimeter per second (cm²/s). 1 stokes is a kinematic viscosity of a fluid with a density of 1 g/cm³ and a dynamic viscosity of 1 poise.

What does cSt viscosity mean?

Kinematic Viscosity (ASTM D445/ISO3105): 1 centi-Stoke (cSt) = 1 mm2/s. Absolute Viscosity is a measure of a fluid’s internal resistance to flow and may be thought of as a measure of fluid friction and of the oil’s film strength to support a load.

Is cSt same as cPs?

What is cSt in lubricants?

The first unit is the centipoise (cP). The other unit is the Centistoke (cSt) which is used to report the kinematic viscosity of motor oil at high temperatures. The number reflects the time required for a fixed amount of fluid to flow through a certain sized orifice on the testing device.

What is the difference between cPs and cSt?

The unit of measure of kinematic viscosity is Centistokes (cSt). A basic difference between the dynamic and kinematic viscosity measurements is density. Kinematic (cSt) x Density = Dynamic (cP) Dynamic (cP) / Density = Kinematic (cSt)

How to calculate the viscosity of a centistoke?

Ut = U100°F (1 + 0.000061 (t – 100)) (1) U100°F = Saybolt Universal viscosity at 100°F in Saybolt Universal seconds equivalent to kinematic viscosity in centiStokes at temperature t (°F) Fluid Mechanics – The study of fluids – liquids and gases.

How are CST units used in ISO viscosity classification?

The ISO viscosity classification uses mm2/s (cSt) units and relates to viscosity at 40oC. It consists of a series of 18 2viscosity brackets between 1.98 mm /s and 1650 mm2/s, each of which is defined by a number. The numbers indicate to the nearest whole number, the mid points of their corresponding brackets.

Which is the equivalent viscosity for 100°C?

Equivalent viscosities for 100° & 210°F are shown SAE 90 to 250 and 20 to 50 specified at 100°C. ISO viscosity classification system Many petroleum products are graded according to the ISO Viscosity Classification System, approved by the international standards organization (ISO).
