Fire contains a built-in library of pipe materials that includes cast iron, copper, steel, PVC, and many others. In addition, the pipe length, nominal size, material type, and fitting quantities and types must be entered for each pipe section.
If sprinkler heads are located at the pipe nodes, then the sprinkler K-factor must be given. The pipe data requires that each pipe section be defined as having a beginning and ending node number. The general project data includes the project name and location, the client name, sprinkler specifications, hazard description, density requirements, hose stream allowances, hydrant test data, and other such data. Two types of data are requested: general project data and pipe segment data. Upon completion of the input process, all data is saved and can be reviewed and edited whenever desired. If using Autodesk Building Systems or AutoCAD MEP (32-bit only), Fire can take data directly from a CAD drawing file.

The user manual lists all the pertinent equations to allow full manual verification.Īll input is checked at the time of entry so that no improper data can be entered.
Calculations can be made for a given water supply pressure or they can be performed such that Fire determines the lowest water supply pressure that adequately drive the sprinkler system. Calculation Methodįire uses the Newton Raphson matrix solution technique to solve pipe networks, where each pipe is defined to flow according to the Hazen Williams formula. The report format is designed to aid both the designer and the plan reviewer. Meters and standpipes can also be analyzed.įire calculates the gpm water flow and velocity through all pipe sections, the gpm flow and residual pressure at each sprinkler head, the pressure losses incurred in each pipe section due to both friction and elevation changes, the maximum system demand pressure, and the total water gpm demanded by the system. Fire can handle all types of sprinkler systems (trees, grids, and hybrids) with up to 1,000 or more sprinklers and pipes. Fire also estimates sprinkler head requirements, calculates optimal pipe sizes, and automatically performs a peaking analysis. Elite's Fire Program quickly performs all necessary hydraulic calculations as required by the National Fire Protection Association (NFPA 13).
