Viscosity
Viscosity is of primary importance in the design and selection of a wide range of products for the Petroleum, Petrochemical, Pharaceutical, Food and Beverage Industries. The viscosity of many petroleum fuels is important for the estimation of optimum storage, handling and operating conditions. Accurate determination of viscosity is essential to many product specifications.
