Calculate upstream relieving pressure:
*Pa [psi-a]
-
Calculate Coefficient for critical flow equation:
-
If heat absorption factor is entered, go to step 8.
-
If normal pressure is not entered or normal temperature is not entered, a message appears: "Please enter heat absorption factor or normal pressure and normal temperature".
-
Calculate Gas temperature at relieving conditions:
-
If vessel wall temperature is not entered, the following message appears: “Please enter heat absorption factor or vessel wall temperature”
-
Calculate heat absorption factor:
-
Estimate Required effective discharge area:
-
If normal pressure,normal temperature, molecular mass, or vessel wall temperature is not entered, a message appears: "Maximum discharge cannot be calculated because normal pressure or normal temperature or molecular mass or vessel wall temperature is not entered". Then go to step 11.
-
Calculate maximum discharge:
Pa [psi-a], W[1b/h]
-
For rupture disk application, calculate required effective discharge area:
