After going through many threads and from my previous knowledge I have a good idea of what is going on, but I would like some concrete calculations to back me up. I am designing a very simple pressure relief valve. It consists of a spring, a disc, and a nozzle. The spring and disc experience atmospheric backpressure here, which is 14psia.
I found that the valve opens up 23psig . If I operate the set up at a high altitude, thus lower atmospheric pressure, 3psia for example, will the valve now open at 14psig? Perhaps I am over simplifying? What would the calcs be?
