How do I get a DEMO ?
Very easy. Click the Demo button in the top left corner of this page and it will take you to the download page. You will see a table with three rows and three columns. Each row represents a different DEMO with the download links located in the middle column.
Can I get the software by email ? How long does it take ?
All the files required for running the software are compressed into a
single self-extracting executable file that is easily transmitted as an
email attachment. Normally you can receive and install the software within
minutes after we receive your order - including the time it takes for it to
download to your computer.
Why do I need the Residential Fire Sprinkler hydraulics package?
That's because residential sprinkler hydraulics are treated differently in the fire sprinkler industry :
Sprinkler discharge, area per head and density are the primary NFPA-13D design criteria for residential sprinkler hydraulics.
Domestic demand, rather than inside hose, is added to residential sprinkler flow.
Residential pipe fittings differentiate between "tees on a branch", "tees on a run" and "couplings".
Residential sprinkler hydraulics must be able to handle Static Pressure as the only available water supply data when there is no information on Residual Pressure and Flow.
You definitely need the package if your company specializes in the design and installation of residential fire sprinklers as per NFPA-13D and NFPA-13R.
What's the difference between Commercial 4.4
and Commercial 5.9 For Windows ? Commercial 5.9 is twice as fast and twice as accurate as Commercial 4.4. There are more features for pump analysis and selection.
It also works on 64-bit computers equipped with Intel's 64-bit Itanium or AMD's Opteron and Athlon 64 chips running under
Windows 2005 Standard x64, Windows 2005 Enterprise x64, Windows XP x64 and Windows 7 x64.
HYDRONICS features impressive state-of-the-art custom controls that put you in charge of all the data entry and editing requirements for your Fire Sprinker Hydraulic calculations. It features pull down menus and scrollable spreadsheets linked to button bars for copy, paste, repeat, replace, insert and delete operations on multiple or single blocks of nodes and pipes. Typical values can be easily entered for multiple nodes and pipes. Click a button bar to repeat lines or columns in the spreadsheet. Clicking on the printer icon sends input or output data to the printer. Losses for meters and backflow devices are entered in psi. The system can be balanced for a minimum end-head flow or pressure.
A single mouse click checks for errors, starts the calculation and displays the output. HYDRONICS uses finite element analysis in conjunction with the Newton-Raphson and LaGuerre algorithms for quickly and accurately balancing any fire sprinkler system configuration.
Cover Sheet - easily created and automatically updated.
Report Submittal - your final report is printed using the neat and attractive NFPA-style
Submittal Reports with the N1.85graph and cover sheet.
Grid Estimator - quickly builds very large systems of cross mains and branch lines. The data created can be easily modified, saved and calculated from the editor.
Automatic Peaking - automatically peaks and selects the MRA for grid systems that are defined by the Grid Estimator or those manually entered using the full screen editor. It prints a Peaking Summary sheet.
Velocity Analyzer - calculates measures of fluid turbulence such as Moody's f and the Reynold's Number. The analyzer calculates and compares friction losses using both the Hazen-Williams and Darcy-Weisbach formulas to help you analyze and solve velocity problems. Settle velocity arguments with this powerful tool.
K-Factor Calculator - calculate adjusted k-factors for arm-overs and drops.
Tank Flow Utility - allows users to modify or add to the built-in pipe diameters, fitting symbols, symbol descriptors and equivalent lengths.
Pipe Table Editor - allows users to modify or add to the built-in pipe diameters, fitting symbols, symbol descriptors and equivalent lengths.
The Velocity Analyzer Utility calculates the Reynolds Number, a key measure of fluid turbulence and
non-laminar flow. The Reynolds Number is a function of pipe diameter(in), flow(gpm) and kinematic viscosity(Sq-Ft/sec).
The Velocity Analyzer uses the Reynolds Number and measures of pipe roughness to calculate Moody's f and pipe friction loss(psi/ft) using the Darcy-Weisbach equation.
The Velocity Analyzer also displays pipe friction loss using the Hazen-Williams equation.
The Tank Flow Utility is used for estimating the
total pressure, velocity and flow from a water tank. The total pressure estimate
takes into account vapor pressure, atmospheric pressure and water pressure. Vapor pressure is related to water temperature
selected from a drop down list box. Atmospheric pressure varies with the value entered for elevation relative to sea level. Water pressure depends
on the value entered for the tank water level relative to the spout centerline. The flow depends on the values entered for spout diameter and a
coefficient for entry and exit losses. These parameters play an important role in matching tanks with fire pumps.
Commercial 5.9 for Windows features an Advanced Pump Selection Dialog that
automatically calculates the pump rated pressure and pump rated flow. It
plots the pump curve and keeps track of important fire pump discharge and
suction parameters. The Net Positive Suction Pressure Available is calculated
using elevation pressure losses(Hz), underground piping friction losses (Hf)
and fixed losses between the source and pump suction.
HYDRONICS provides you with immediate and comprehensive summaries of the
hydraulic calculation output that can be viewed on your screen or sent to
the printer. You can easily keep track of the friction loss,
flow and velocity for every pipe in your sprinkler system.
