Dear Gents,

The flange leakage calculation report added in CAESAR II 5.1 is a very convenient function to make a simple report in a short time.

However, I have recently noticed that the calculation report does not include design pressure (Pmax - should be the maximum of P1, P2, P3, etc...) in the evaluation as follows:

Peq = F / (pi * G^2 /4) + M / (pi * G^3 / 16)
Peq <= Maximum Operating Pressure per ASME B16.5 (per CAESAR II 5.1)
Peq + Pmax <= Maximum Operating Pressure per ASME B16.5 (per Peq method)

Please advise if I am misunderstanding some factors in the calculation.

Regards,
Yung Lee
