The SI unit of dynamic viscosity is the newton-second per square meter (N·s/m ), also frequently expressed in the equivalent forms pascal-second (Pa·s), kilogram per meter per second (kg·m ·s ) and poiseuille (Pl). The CGS unit is the poise (P, or g·cm ·s = 0.1 Pa·s), named after Jean Léonard Marie Poiseuille. It is commonly expressed, particularly in ASTM standards, as centipoise (cP). The centipoise is convenient because the viscosity of water at 20 °C is about 1 cP, and one centipois… SpletStating an oil’s viscosity is meaningless unless the temperature at which the viscosity was measured is defined. Typically, the viscosity is reported at one of two temperatures, either 40°C (100°F) or 100°C (212°F). For most industrial oils, it is common to measure kinematic viscosity at 40°C because this is the basis for the ISO ...

Splet28. dec. 2024 · Saybolt viscosity, also called SSU viscosity, is measured with a Saybolt viscometer, which heats the liquid to a desired temperature and pours it through a calibrated orifice. Standard test temperatures are 77, 100, 122 and 210 degrees Fahrenheit (25.0, 37.8, 50.0 and 98.9 degrees Celsius).
