The FHC hydraulic calculation software has been used to design thousands of fire sprinkler systems through the world. From complex petrochemical plants, huge automated logistic facilities, aircraft hangers, manufacturing plants to a domestic house, whatever the project FHC will be able to help. Welcome to the Simple Hydraulic Calculator (SHC for short).SHC is a powerful, flexible, and full featured fire sprinkler hydraulic calculation program designed from the ground up for automatic sprinkler system designers and engineers.

HASS ( Hydraulic Analyzer of Sprinkler Systems), developed by mathematicians and registered professional engineers, was first licensed in 1976 as a tool for easy use by engineers, sprinkler contractors and reviewers alike. Risunki protiv kureniya. HASS, typically licensed in five year increments, gives you the tools you need to determine water supply adequacy based on system demand and distribution piping. With HASS, you can perform hydraulic analysis in accordance with NFPA 13, 13D, 13R, 14, 15, 20, 24, 750 and other standards, calculating any connection of nodes and pipes. You get major revisions, year in and year out; improvements or new features at no extra charge for the duration of the license period. You can use HASS for calculations with either the Hazen-Williams formula or the Darcy-Weisbach formula using total or normal pressure friction loss considerations. Darcy-Weisbach is used where specified (e.g.

Antifreeze systems, water-mist systems, flow of foam concentrate and other liquids), while Hazen-Williams is used for sprinkler systems (grids, trees, and loops), water spray fixed systems, standpipe systems, yard main (hydrant) systems, AFFF systems, and any other flow of water through pipes under pressure.. Systems with multiple sources, multiple pumps (with a tank, reservoir, or public main), or multiple fixed pressure loss devices or multiple riser feeds. With either formula, there is no limit to the K-factor of the flowing nozzle, pressure reducing valve or sprinkler.

You can readily adjust pipe sizes as you optimize the design. HASS gives you more than just the ability to calculate. For gridded systems, the Grid Estimator gives suggested sizes, and automatically generates node and pipe data. Similarly, the Tree Generator gives node and pipe data using the ordinary hazard piping schedule, or uses pipe sizes you specify.

When you use the System Builder, you can combine pipe segments into branch lines, locate cross mains and riser nipples, then let the System Builder automatically generate node and pipe data.. Ideal for more complex piping arrangements such as multiple cross main grids. (In each of these cases, the Pipe-to-Source Option lets you tie the system to the source before generating data.) HASS gives you a battery of Options, Utilities, File and Search abilities, so you can develop equivalents for a K-factor, branch line, rolled grooves, or fitting lengths as well as summarize flow test results, merge two data files, renumber node/pipe tags in sequential order, set program defaults and adjust various operational range settings. HASS is available in English or Spanish language formats with English or Metric units.
