LPIPE ( aka LIQTHERM-Lite) is a steady state, hydraulic simulation software for liquid pipelines under isothermal (constant temperature) flow. It is a scaled-down version of the LIQTHERM software. Multiple pump stations (Maximum of 5 pump stations ) along the pipeline with pumps in series or parallel at each station may be modeled. The latest version of this software can be run on Pentium and AMD based computers with a minimum 128 MB RAM running Microsoft Windows 2000, Windows XP or Vista.
