Ketchup has a viscosity of 1000 cP at 30 degrees Celsius or. The effect of the temperature on viscosity is clearly evidenced in the drastic drop in viscosity of water as the temperature is increased from near ambient to 60 degrees Celsius. Summary of Test Method: The viscosity index of an oil is calculated from its kinematic viscosities at 40 and 100☌ determined according to EN ISO 3104. Air kinematic viscosity at varying temperature and constant pressures (1-10 000 bara, 14.5 - 145 000 psia): Back to top Air dynamic and kinematic viscosity at gas-liquid equilibrium pressure: Back to top. 2 lists the dynamic viscosities of several liquids at various temperatures in centipoise. This practice covers the procedures for calculating the viscosity index of petroleum products, such as lubricating oils, and related materials from their kinematic viscosities at 40 and 100☌. Viscosity Index is sometimes used to characterize base oils for purposes of establishing engine testing requirements for engine oil performance categories. The viscosity index is used in practice as a single number indicating temperature dependence of kinematic viscosity. The viscosity index is a widely used and accepted measure of the variation in kinematic viscosity due to changes in the temperature of a petroleum product between 40 and 100 ☌.Ī higher viscosity index indicates a smaller decrease in kinematic viscosity with increasing temperature of the lubricant. The LMNO Engineering calculation takes the user input temperature and extracts viscosity from the graph on page A-5 in Crane (1988), performing linear.
