Welcome to the Simple Hydraulic Calculator (SHC for short). SHC is a powerful, flexible, full featured hydraulic calculation program designed from the ground up for automatic sprinkler system designers and engineers.

SHC can hydraulically calculate your sprinkler systems using the Hazen-Wiliams and Darcy-Weisbach friction loss equations in accordance with NFPA 13 and other standards. Any piping configuration is supported - trees, loops, grids, and completely custom layouts. You may even use multiple water sources, pumps, and backflow preventers. For a complete list of SHC's calculation abilities visit the feature list page.

SHC uses a powerful, flexible, and fast method of data entry. See the data entry page for more information.

Evaluating your sprinkler system design is even more important than entering the data. SHC has the tools you need! See the calculations page for details.

And SHC doesn't fall short during submittals. Professional looking code compliant hydraulic calculation reports can be printed or saved as industry standard pdf files. Learn more on the reports page.
