When pumping any liquid, it's important to understand properties such as specific gravity. Also referred to as relative density, specific gravity is the ratio of the densities of one fluid at a known temperature and pressure to a reference fluid at a specific temperature and pressure. In this video, we demonstrate the concept of specific gravity, and show how it relates to density. If you've enjoyed this video, consider registering for our on-demand Introduction to Pump & System. This collection of six training modules is designed to provide attendees the introductory knowledge on all aspects of the pump, system and components (including drivers). Any person who is interested in or sees themselves as a future employee in the pump or fluid handling industry will benefit from this training.
