Hi all I want to derive equation to determine time to fill gas in closed vessel. - Gas will feed to vessel with constant pressure at P1. - Gas will feed to vessel until pressure vessel reach to feed pressure Pi-->P - Time to fill gas in vessel until pressure vessel = feed pressur is required. I...

the gas (s. below) under pressure of 190 bar flow within a pipe which contain a air at atomspare pressue. How I can calculate the UFL of the gas mixture composed: Component Mol% N2 1.2245 Methan 69.2390 Carbondioxide 5.7844 C2 10.6640 C3...

Yes, but the valve ball has flowen away and the valve body pretty ruptured.

The pipe didn't ruptured but blow up. Could you tell me the equation to calculate the internal pressure. Our lab has measured the hardness and found HV 253, is there any relation with internal pressure. Thanks for help

Thank you very much for your replay, but could you tell me where you got this statment ,,until that gas is about 1/2 the pressure of the upstream,, thank you again.

hi all, thanks for the answers. I am doing accident analysis this why I need to calculate the overpressure of the explosion. I thought I can calculate the pressure using the proprieties of the material but I don't know what is the relationship.

Hi all, Could you tell me how I can calculate the temperature of pressured air in a 2" pipe by hydrocarbon gas with a pressure of 190 bar.

Hi all, Could you tell me how I can calculate the overpressure in 2" pipe API 5L X52 which cause blown up of the pipe by 50%.

Hi all, I am new here and need your help. After sudden opening of a ball valve with cross section area of 10 mm come to an blow up (explosion) of the 2" pipe. (before opening) Up stream the valve was the gas pressure 190 bar during downstream the pressure was 0 bar, however it was air inside...
