Thermal Relief Valve Calculation

[TheHub]

We are in the process of performing a thermal relief valve calculation and have found no good reference to check the calc. Can anyone provide general equations and a reference for this?

Thanks

Also the ASME Code,both Section III and Section VIII have articles dealing with sizing of relief valves (Section III, Division 1, Articles NB-7000, NC-7000 and ND-7000 "Overpressure Protection" and Section VIII, Parts UG 125 - 137 "Overpressure Protection&quot
