Feature List

Simple Hydraulic Calculator contains all the features you need to enter and calculate any sprinkler system.

Advanced Hydraulic Calculation Engine

Hazen-Williams friction loss formula
Darcy-Weisbach friction loss formula
Simultaneous Hazen/Darcy mixed formula - calculate part of a system with the Hazen-Williams formula and part with the Darcy-Weisbach formula
Demand calculations (start with the system demand)
Supply calculations (start with the water supply to the system) with optional safety margin
Calculate any piping configuration - loop, tree, grid, or completely custom
Suitable for many suppression system designs including wet, dry, pre-action, deluge, antifreeze, low, medium, and high pressure mist, foam-water, foam concentrate and more!
Multiple water supplies fully supported
Multiple fire pumps supported
Multiple backflow prevention and fixed loss devices supported
Can adjust water supply and demand to base of system riser or any other node
No artificial limit on number of pipes or nodes (greater than 2000 permitted)
Fitting loss coefficient K support (for non-sprinkler work)

NFPA 13-07 and 13-10 (the fire sprinkler installation standard) compliance capable
Automatically adapts to paper size
Customizable report page header text
Customizable node analysis information
Customizable pipe information
Graphs and text use color to aid readability (optional)
Export as pdf, html, or plain text - AHJ's do not want to install a custom viewing program just to see your emailed calcs!

Real time error checking
Automatic "proposals" for fast data entry
Descriptive node and pipe names up to 8 characters long
"LiveLook" information bar for quick system evaluation
Robust U.S. and SI unit support - even mixed U.S. and SI units supported
Group editing of selected values by type (size, length, elevation, k-factor, etc.)
Multiple undo and redo
"Popup" helpers for remembering/using material codes, fitting codes, etc.
Undefined and unused node list
User selectable font
User selectable highlighting colors

All system, node, and pipe information displayed in tabular format for comprehensive system analysis
Pipe and node information sortable by any value
User selectable pipe information columns
Fully resizable window, displays as much information as it can
Persistent - you may keep this window open and in view while editing input data!

View properties and internal diameters of any defined material
Edit properties and internal diameters of any material (except default "schedule 40 steel" piping material
Enter entirely new pipe materials

Import DXF files - the format supported by most CAD applications
Automatically define pipes and nodes from drawing's "line" and "lwpolyline" ACAD entities
Automatically searches "text" entities for nominal pipe sizes
Full preview of generated commands before committing them to the input data
Update DXF file after calculation
- Updated nominal pipe size "text" entities to match SHC's data file
- Add "text" for node and pipe labels
- Add "text" for node discharge
- Add "text" for pipe flow rates
- Add pipe flow direction arrows

Quick Start wizards for fast creation of basic tree and gridded systems with water supply
View the hydraulic demand graph and save as jpg, wmf, or bmp file
View the flow diagram and save as jpg, wmf, or bmp file
Easily and quickly convert existing files to different units
Backflow prevention device database for easy insertion in the data input file

SHC is shareware. Try it before you buy it - anonymously - we want you to!
SHC does not expire and uses plain text data files. What this means for you -
- NO ANNUAL FEES!
- NO VENDOR LOCK-IN! Have you ever been forced to pay a quarterly or annual "maintenance" fee or risk losing access to YOUR data files? Some vendors try this trick. Not Igneus Incorporated. We're on your side!
