Foam system calculations

Abstract

Foam is a stable aggregation of gas-filled bubbles formed from a homogeneous mixture of water and foam concentrate in predetermined proportions. Foam fire protection is well suited for the control and extinguishment of specific types of fires especially those involving certain arrangements offlammable and combustible liquids. Foam is generally lighter than flammable/combustible liquids;therefore it floats on the liquid surface producing a layer which has multiple advantageous effects.These effects include vapor-sealing of theliquid, cooling of the liquid surface, and limitation of oxygen to the liquid surface.
