Density and Specific Gravity How they affect pump

May 08, 20140183;32;As it is a ratio, specific gravity is unitless. A fluid with a specific gravity of less than 1 would be considered lighter than water, while a fluid with a specific gravity greater than one would be considered heavier than water. So how do specific gravity and density affect pump sizing and selection? Let us explain.
