• One pipe can represent multiple parallel pipes (useful for tube bundles)
• Enhanced fittings & losses entry for pipes
• Insulation can be included on inside of pipe/duct and effect on flow area and heat transfer can be modeled
• Insulation can now be applied even when there is no heat transfer

Junctions

• Compressor/fans can be modeled as head rise in addition to pressure rise
• Compressor/fans can be modeled as fixed head or pressure rise
• Compressor/fan speed control for suction pressure (discharge pressure still supported)
• Compressor/fan speed control if pressure is exceeded high or low
• Compressor/fan special condition open in addition to closed
• One compressor/fan can represent multiple in parallel or series
• Can calculate compressor/fan energy usage and cost
• One-Way Valve split into two junction types - Check Valve and Relief Valve
• Valves now support Cv vs. percent open (like Control Valves)
• More advanced control valve logic
• Junction data can be modified through an Excel file

Solver

• Fluids can be modeled in multiple loops with heat transfer
• Heat exchangers can exchange heat with heat exchangers from separate loops which may have the same or a different fluid
• Internal insulation can be added to a pipe or duct, and reduced flow area and thermal effects (if they are modeled) will be automatically calculated
• New equation of state feature to model density as a table of curve based on pressure and temperature (similar to the previous enthalpy table)

Workspace

• By dragging right to left during selection, it selects anything it touches or encompasses
• Renumber Increment added
• Shortcut button provides fast access to explanations of shortcut functions
• Selections can be rotated right or left
• New window added to show all undefined pipes and junctions and missing properties
• New Zoom to Fit feature

Model Data

• Can see data for all scenario direct ancestors on Model Data

Output

• Can view output for multiple scenarios in Output at same time
• New Tank Summary
• Equivalent orifice area/diameter displayed for valves/control valves
• Heat exchanger secondary fluid outlet temperature and log mean temperature difference displayed for certain models
• Quick graph of internal pipes results available directly from Output window
• Specific volume now an output parameter
• Saturation temperature available for each mixture component
• Users can print Model Data with output

Graph Results

• Copy x-y data to clipboard
• Can plot profile graphs for multiple paths
• Customize feature for graph colors added
• Improved compressor/fan vs. system curve generation for series pumps

Visual Report

• Show the design factors on the Visual Report
• Can change the font and size for the title, legend, etc., independently
• More automatic updates of Visual Report added

General

• Suggest compressor/fan will search user specified database for compressor/fans which can meet operating point
• Significantly enhanced global editing of pipes and junctions (data now shown in categories)
• Batch runs for scenarios
• All printing can go directly to a PDF file
• In grids, cells that have drop-down capability have a persistent drop down symbol
• Feature to reorder scenarios in Scenario Manager
• Initialization and data files now saved to user folders

GSC Module - Optional Add-On

• Extend Arrow's control capabilities to include remote sensor control

CST Module - Optional Add-On

• Obtain cost for entire pipe system (has all cost capabilities of AFT Titan™)
• Account for non-recurring and recurring costs
• Obtain non-recurring material and installation costs from RS Means™
