Compressed air foam system flow rate issues
Thread Content
I would like to ask the experts here: in a compressed air foam fire extinguishing system, how does the flow rate change when air is mixed with the foam mixture? For example, when a foam mixture with a flow rate of 10 L/s is mixed with compressed air at 50 L/s, is the theoretical flow rate 60 L/s? Can the foam expansion ratio reach up to 6 times? I’ve looked up a lot of information but couldn’t find any relevant theories; I need help! !
There’s also the pressure issue; theoretically, it’s not possible to reach 60 L/s
