How do you convert centistokes to SSU?
Example: Converting Centistokes to SSU Viscosity Calculate 4ac = 4 × 0.226 × -195 = -176.28. Calculate 2a = 2 × 0.226 = 0.452. Calculate SQRT(b2 -4ac) = √1076.28 = 32.81. Calculate SSU viscosity t = [-b + SQRT(b2 -4ac)] / [2a] = 138.9 seconds.
What is CS in viscosity?
The “cgs” unit of kinematic viscosity (one centimeter squared per second), is called one stoke (St). 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).
What is centistoke oil?
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 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.
Is higher viscosity thicker or thinner?
In layman’s terms, viscosity defines a fluid’s resistance to flow. The higher the viscosity of a liquid, the thicker it is and the greater the resistance to flow. Temperature will affect the viscosity of most materials.
What ISO is AW46?
AW 46 hydraulic fluids have an International Standards Viscosity Grade or ISO VG of 46. This is the thickness of the fluid tested at 40 degrees Celsius. ISO VG 46 is the most popular grade due to its middle grade flow properties with a thickness that is equivalent to a SAE 15 weight lubricant.
What does AW46 mean?
For example, AW 46 hydraulic oil is used to operate the hydraulic systems in off road equipment such as dump trucks, excavators, and backhoes, while AW 32 hydraulic oil colder weather application, like in a snow plow’s pump.
What does a centistoke measure?
What is the viscosity of hydraulic oil at 100 degrees?
Viscosity at 100°C Viscosity at 100°C Viscosity at 40°C Viscosity at 40°C Motor oils and hydraulic oils ISO grade ISO grade ISO grade SAE grade range (cST) ISO grade range ISO grade range ISO grade range 5 3.80-* 32 28.8-35.2 10 4.10-* 46 41.4-50.6
How do you calculate viscosity of fuel oil?
Fuels oils – and their viscosities versus temperature. Sponsored Links. Saybolt Universal Seconds – SSU – viscosity versus temperature for typical fuel oils: T F = T C 9 / 5 + 32. SSU (Saybolt Universal Seconds) = centiStokes (cSt) x 4.55 1)

What is an ISO viscosity grade number?
Each ISO viscosity grade number corresponds to the mid-point of a viscosity range expressed in centistokes (cSt) at 40°C. For example, a lubricant with an ISO grade of 32 has a viscosity within the range of 28.8-35.2, the midpoint of which is 32.
