IntroductionPipe Size Optimization for Carbon and Stainless Steel PipesThis spreadsheet is designed to utilize the "Solver" within Microsoft Excel 97 or higher. Be sure to activate the macrowhen opening this sheet. The macro is designed to enable the solver automatically. Click on the worksheets marked"Carbon Steel" or "Stainless Steel" at the bottom of this page. Enter the information in the yellow cells and click on"Calculate". The spreadsheet will calculate the economic optimum pipe diameter and velocity for your system. The onlyinputs needed are the fluid's viscosity, density, and the flowrate. Easy as can be!The algorithm within this spreadsheet is based upon research performed by the following people and published in theMay 1999 issue of Chemical Engineering magazine:Alejandro Anaya DurandJorge Arroyo BoyJoaquin Lastra CorralLuis Ojeda BerraJose Suarez TruebaPedro Villalon BrenaThe article entitled "Updated Rules for Pipe Sizing" can be found on pages 153-156. Derivation and a more in-depthanalysis of this algorithm can be found in this resource.Chris (author of The Chemical Engineers' Resource Page)
