The system is already designed... i wanted just to double check backpressure downstream the PSV valves and i have just asked feedback on how to calculate flow rate of CO2 gas flow... not to design the system, but anyway... you're right...maybe i shouldn't ask such kind of info trhough a forum...
The flow will occur in case, during CO2 discharge for fire extinguish, pressure in the line will go for some reason above 170 Barg (PSV set point). Under this circumstances I will have flow through the system (CO2 nozzles) plus flow through the 2 PSV valves which will relieve the pressure. I...
Hello guys,
I need to calculate the flow rate for the following system. 2 lines of CO2 cyclinders at 60 bar. Each line (1/2'') goes to a 1/2'' PSV valve. Downstream the 2 PSV the line are collected together into 1'' pipe.
The two PSV are identical and as per datasheet they have the following...
