Hi
Unsure where to go with this now. I am modelling a system where the diameters of the pipes are different and have 13 equations with 13 unknowns
I am modifying an example from a textbook to suit my requirements. (Cengel and Cimbala's Fluid Mechanics Fundamentals and Applications 2nd ed. Page 375) but It's been a while since I have used MathCAD and I'm not an expert in getting it to work. Any help is appreciated.
