NCPI Toolbox 2013
NCPI Toolbox is a group of three NCPI-developed programs that provide engineers tools for calculating Trench Load, Hydraulic Flow and Leastcost.
Trench Load is a design program incorporating Marston's equations for soil loads on rigid conduits and the latest ASTM requirements.
Hyflow utilizes Manning's open channel flow equations to determine hydraulic solutions. By entering the desired flow rate and slope, the recommended pipe diameter with depth of flow is instantly displayed.
Leastcost uses historic inflation and interest rates together with life cycle analysis to provide an equitable cost comparison between various materials options over the service life of an installation.
