Using Centrifugal Separators for Oil Reclamation

Using Centrifugal Separators for Oil Reclamation

A tube centrifuge has continuous discharge of both light and heavy fluids. It also separates particulate but will quickly fill up with solid matter when the percentage is much more than 0.5 percent. This type of centrifuge must be disassembled to remove particulate and is more labor- intensive when the fluid contains a high percentage of ...

Lesson 11: Force Pressure and Head Calculations

Head - Vertical distance or height of water above a reference point. It is usually expressed in feet. It is a basic fact of science that 1 cubic foot of water weighs 62.4 pounds and contains 7.48 gallons. An important point to remember is that force acts in a particular direction; water in a tank exerts force downward on the bottom and out the ...
