Kathy, I don’t understand why are you asking this question it applies to the testing and certification of pressure vessels. This would be something that an engineer designing a filter system would be concerned with. And would already be addressed by a filter manufacturer in order to insure that it would operate with it’s intended operating pressure. I believe this may be what you are asking for, the pressure delta in a filter system would be the difference between the inlet pressure and the outlet pressure. If you have more than a 10 psi pressure drop from the inlet of a filter to the outlet then it is time to change the element inside. Hope this is what you are after if not please give me a little more information about what your intent is. David
