Wanted to say thanks for keeping such a great backlog of videos! These have come in great as I study for my FE & PE. It's nice to see how these networks work out by hand -- I'm used to using a few different specialized programs to handle our gas pipeline networks; last time I checked our model has ~302,000 nodes and just shy of 310,000 individual pipes, not a fun prospect for manual calculation. I still occasionally switch to Excel for "rough" calculations, it's easier to use some of the industry standard equations that aren't iterative. Modern software also now includes slow time variance and unsteady state modelling, as well as considerations for composition changes (hydrates, water content & dropout), supercompressibility & rarefaction, and multiphase models. Thanks again for the videos!
Appreciate your comment -- thank you! And yes, we're fortunate to have more sophisticated tools than spreadsheets for large networks and unsteady flows!
