What does SSU mean in viscosity?

What does SSU mean in viscosity?

Saybolt Universal Seconds
Saybolt Universal Seconds, SSU, is the kinematic viscosity as determined by the time in seconds required for 60 cc of fluid to flow through a standard orifice.

What is the viscosity of water in SSU?

What does SSU mean for oil?

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 is the SSU of water?

How do you convert cSt 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 oil SSU?

Viscosity rating is a measure of the oil’s resistance to flow or thickness, and is the single most important characteristic of hydraulic oil. 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 Number 2 fuel oil?
