Pressure compensation elements

Hello,

I am currently looking at pressure compensation elements and how to choose the right one. Basically, I would like to have something like an Excel sheet in which the following data is entered.

- air volume inside the component/part
- temperature range
- sealing pressure
- air flow of pressure compensation element (PCE)

Based on that, a graph indicating if the pressure element is OK for the application should be calculated.

Now, the pressure w/o PCE should be relatively easy to calculate. However, thinking about the next step, I am wondering if it is possible to find an approximation for the non-linear behaviour of PCEs (more pressure inside-more volume flow, and with reducing pressure less volume flow until pressure compensation)at all?
I am trying to use Excel because not everzone has more suffisticated software at hand. Moreover, I know that such calculations may be performed by suppliers. However, this often takes time. Thus, I was trying to find something giving a good approximation for the first shot. Hope that makes sense.

So, my two questions are:
1) Is it possible at all to create something like described?
2) Is ist possible in Excel?

Many Thanks and Kind regards
Mike
