The flow through a safety valve vent stack system has been modeled and analyzed theoretically and experimentally. The theoretical analysis is based on the well known Chapman-Korst base flow theory. The base flow model is augmented with an empirically determined recompression factor to improve agreement between the theoretical analysis and experimental results. A computer program has been developed to solve the equations and provide necessary information to designers.
