Well, the idea it's to be able to generate a cavitation graph for PRVs. I usually use a specific website to design and find the right diameter for PRVs (bermad-sizing.com), it turns out that the input parameters on the website are pretty basic, like upstream and downstream pressure, maximum and minimum flows. It would be really pratical if i can just set the parameters on PRV (diameter, pressures, etc.) and i can vizualize a ghaph indicating a risk of cavitation for the PRV.
