Question to be practised

High $-$pressure liquified $C{O}_2$ is stored in a system for use in process.

This $C{O}_2$ would released to be used in process pipeline of $0\mathrm{.}5in.$ A

pressure relief needs to be designed to protect from overpressure

scenario. Determine the vent area required for a spring type relief

valve, assuming a set pressure of $20g$ and an overpressure of $10\%.$

Liquefied $C{O}_2$ saturation vapor pressure: $800$ psia.

Temperature: $80F.$
