Two-Phase PSV Sizing: Omega Method & Maximum G-Flux Calculation | API 520 & 521

Описание: In this video, I explain the Omega method for calculating maximum mass flux (G-flux) for two-phase pressure safety valve (PSV) sizing, following the relevant guidelines of API 520 and API 521.
The video covers the difference between gas and two-phase critical pressure ratios, the calculation of the Omega parameter, determining the critical pressure ratio according to API 521, and calculating the maximum G-flux according to API 520.
