The Pressure Relief Valve Sizing Calculator application is used for calculation sizing of a pressure relief used in refineries, chemical facilities and related industries to able to vent any source of liquid so that the pressure within the protected apparatus cannot exceed the maximum allowable over pressure. Sizing for liquids relief largely follows the API RP 520 procedures.

Features
• Calculate pressure relief valve sizing for liquid.
• Calculate the required sizing area, orifice sizing, pressure relief valve capacity
• Liquids can be selected from the list or custom properties fill for calculation the sizing of a pressure relief valve of vapor
• The unit of mass flow, volume flow, pressure, temperature, density can be selected.
