I dont know if i am doing the rigth question to you guys, if you simulate with pipephase in a gas phase option, the program choose by default: moody correlation pressure drop method, i know that it is the for friction factor, but what is the equation for the pressure drop? is it the isothermal...
I have an interesting issue:
We have three (3) storage atmospheric tanks that contain: propane @ -50°F, iso-butane @ -6°F and normal-butane@ 26°F each of one. The tanks are insulated and have a vent header, each tank has a vent valve connected to the header, the valves are control type and...
a question for you guys:if i have a PSV installed (for whatever reason) and it opens ¿what is the flow trough this valve? ¿is the one calculated by a contingency (fire for example)? or ¿is the calculated by the actual orifice with the upstream pressure ?(assuming critical flow).
thanks for the help
