Blowdown prediction of a conventional pressure relief

1. Introduction. A pressure relief valve (PRV) is a pressure relief device designed for the automatic release of a substance from a boiler, pressure vessel, or other system when the pressure or temperature exceeds preset limits to protect a pressure vessel and/or system .Of many types of PRVs, the conventional PRV is one of the most important types.
