Answer (2)

Foam delivery systems include methods like induction, which draws foam concentrate through water flow for effective foam generation. A properly aerated foam exits a nozzle as a foamed solution, demonstrating its unique properties. Understanding these concepts is vital in both industrial applications and firefighting techniques. ;
