I received an email regarding combination fire/smoke damper. But I doubted the explanation. Could anyone give me some ideas about the following explanation? Is it correct?
The concept of fire/smoke damper is derived because it was realised that alot of time people died because of smoke rather...
May I know how does a combination fire/smoke damper works? As I know, combination fire/smoke damper is coupled with a fusible link and an actuator. If there is fire, the fusible link will fuse off and the damper blade will be closed by means of tensioned spring. But, can the actuator open up the...

May I know where can I get a flow coefficient,Cf versus beta (orifice outer diameter/orifice inner diameter) graph? How do I obtain flow coefficient without doing experiment? Thanks for answering.
