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 characteristics: - max volume flow (working condition): 24,669 m^3/h - max volume flow (standard condition): 4265,116 m^3/h - max mass flow: 8372,849 kg/hr First question: Do you think it is possible to calculate the flow rate trhough the 1'' pipe with the datas above? second question: don't you think that 8372,849 kh/hr are a huge quantity considering that all this mass with pass through 1/2'' hole? Thank you very much!
