GASWorkS™ and GASCalc™
Natural Gas Reticulation; Gas Flow Modelling
The GASWorkS software is widely used in the natural gas reticulation industries for the design of industrial and domestic supply networks. Provides Windows based steady-state network modeling tools. It is designed to assist the engineering professional analyze and design distribution, gathering, transmission, and plant piping systems containing natural gas or other compressible fluids. Support is provided for systems made up of fittings, compressors, pipes, regulators, valves, and wells. A robust set of import and export routines allow data exchange with a variety of CAD, GIS, and Database applications. GASWorks offers no fewer than 20 different pipe flow equations.
• Models gas flows in pipe networks
• Design natural gas reticulation systems of city gas, cross country, industrial, commercial etc
• User-choice of gas equations, more than 20 equations are available like, Panhandle, Weymouth, Colebrook, etc
• Simulate regulators, compressors, valves, wells and other equipment
GASCalc is a Windows based suite of tools designed to calculate various parameters associated with gas piping and equipment. It can be used to calculate compressibility, sonic velocity, and other gas properties, orifice, diaphragm, rotary, turbine, and cone meter sizing, pipe size, flow, and stress values, regulator, relief, and valve sizing, compressor and well flow values, vent time calculation, dimensional and energy conversions, lost gas volumes, external loading values, numerous other pressure, flow, and stress related values. It supports a variety of dimensional units and can be used with multiple unit measurement systems.

Natural gas and compressible flow simulation
GASWorkS is ideal for the design and analysis of township or industrial area reticulation system but can be used for any pipe flow system for which the appropriate equation is available or known. The ability to superimpose a pipe network over a map of a township is a powerful feature of GASWorkS. The software operates in any system of units.
Key features of GASWorkS include :
User choice of gas equations
Graphical Data Interface
Modeling of regulators, compressors, valves, wells, fittings and other equipment
The ability to display BMP or DXF images (for example road maps) as a background to the model schematic
Excellent reporting facilities
Directly model network with each pipe length and diameter from .dxf file by only single click
Color coding of pipe network
Valve On/Off facility
Calculates compressor estimated fuel usage rate, power, temperature change, and compression ratio
Calculates coefficient of regulator
Mass update option
Text insert option

Graphical Data Interface GDI
The Graphical Data Interface (GDI) provides map style graphical access to the model data. The GDI allows the inclusion of bitmap (BMP), Drawing Interchange File (DXF), or Shape (SHP) files as a reference background. Using the GDI, the User can draw the model schematic using point-and-click mouse entry, coordinate value entry, or relative distance and angle entry. The GDI provides pop-up data screens for editing and viewing of the various pipe, node and customer data and analysis results.

The GDI includes a wide variety of tools for modifying the pipe, node, and customer model features including routines for adding, deleting and moving features - and the ability to undo accidental changes and deletions. Three independent display panels support various zoom commands including the ability to zoom in by a User specified window, zoom by a User specified scale, and zoom to a previous view allow the User to easily move around the model image. A robust set of color coding & tracing routines enhance the User’s ability to graphically review the analysis results and the system’s performance. The trace routines are complimented by the inclusion of what we refer to as “attribute” valves. The attribute valve feature was developed to assist in the design & layout of emergency isolation areas. A complete set of annotation routines allows the User to include notes and references in the model graphics.

The GDI tools are accessed through descriptive tool icons contained on function based “fly-out” tool bars, through a command line and list interface, and through a floating tool palette which can be arranged, sized, and placed to meet the User’s preference.
The report routines provide spreadsheet style reporting of the model data, attribute data, and analysis results - including the ability to edit data directly from within the report by simply selecting the cell you wish to edit and making the desired change. The User may select the items to be included in the report by collapsing the columns associated with the unwanted items. The pipe report provides a comprehensive collection of information including reporting of both size/type and internal diameter values, reporting of pipe inlet, outlet and average pressures, flow rates, velocities and volumes, and simultaneous reporting of linear and pressure drop per User specified length. Selection sets may be created from

within the standard reports, allowing unique reporting of User specified data groups. Hierarchical queries allow the creation of sub-sets from a previously created selection set.
Import and Export
GASWorkS includes an extensive set of import and export routines allowing data to be exchanged between varieties of applications. Support is provided for ASCII, DBF, Microsoft Access and Excel data files, third party model data files, Arc/Info shape (SHP) files, and a robust DXF translator allowing both import & export of graphical data. The DXF and SHP import routines allow the automated creation of a GASWorkS model from a CAD drawing or GIS data set. “Quick Export” outlines are provided to allow export of complete model data with a single click.
