Knowing the viscosity of a lubricant is critical for condition monitoring. As a result, field-based users need portable viscometers to immediately assess critical equipment while working on-site.

Hypromellose 0.3%, sodium hyaluronate 0.4%, carboxymethylcellulose sodium 0.5%/glycerin 0.9%, and carmellose sodium 0.5% were investigated. Ostwald capillary viscometers were utilised for viscosity ...

Gravimetric Capillary is the most common technique used to measure kinematic viscosity. It is temperature controlled, usually 40 ºC for single grade oils, and both 40 and 100 ºC for multi-grade oils.

In this article, we will consider what viscosity is, how it is measured and the applications of viscometry in the food and beverage industry. When a force or stress is applied to a fluid, it flows, ...
