This relief valve sizing calculator is designed to determine the size of relieve devices for diverse industrial applications using American petroleum institute's equations as a basis for calculation.

The software's features include support for both SI and US units of measurements, allowing for flexible inputs of different measurement units for Volumetric flow rate, Mass Flow rate, Temperature, Viscosity, and Pressure. It also provides a sizing option for both conventional and pilot operated relief valves for gas or vapor relief, liquid relief, saturated and superheated steam relief, and vaporizing liquids (wetted vessels).
One impressive feature of the Relief Valve Sizing Calculator is the ability to evaluate multiple cases in one go, enabling users to save time and effort. The software provides the option to save and load input, copy results, and paste them anywhere in any document. Additionally, there is an option to generate a summary report that can be printed or saved in different formats, such as Excel, Word, and PDF.
Calculated variables are based on input and service, with the following variables computed for all services: Relieving Pressure, Required effective discharge area, Actual discharge area, Equivalent Orifice diameter of device, Installed Relief rate, and Designation. The software displays more calculated variables based on the selected service and input parameters.
In vessel fire cases (Vaporizing liquids - wetted vessels), the Relief Valve Sizing Calculator provides additional calculations. These calculations include the rate of vaporization, the total heat absorption, and the total wetted area. The software supports both vertical, horizontal, and spherical vessel orientation.
Overall, the Relief Valve Sizing Calculator is a very comprehensive software tool that offers immense value to engineers and other professionals working in the field. Its user-friendly interface and advanced features make it an excellent option for anyone looking for a robust relief valve sizing calculator.
