Pumping Flashing Steam Condensate

[KenShumway]

I am looking for tools to help calculate the pressure drop in steam condensate lines with flashing present. I have found a variety of spreadsheets that are helpful, but everything that I've found only handles the calculations for one piping segment with flow and one diameter. I need to be able to model a piping system with branches and multiple size pipes. I have not found a commercial product with these capabilities. Does anyone know of such a product that is available for purchase?
