Modeling Features

Pipes

• Specify diameter, length and roughness or select by material type and schedule from the built-in database
• Select friction modeling from an extensive list including:
  • pipe roughness
  • Panhandle method
  • Weymouth method
• Model heat transfer and add insulation layers – predict insulation surface temperatures to ensure compliance with workplace safety regulations
• Use embedded fittings to reduce workspace complexity

Compressors & Fans

• Explore the interaction of your system with compressors and fans
• Model compressor and fan power and associated energy costs
• Select between fixed specified flow or modeling with a compressor or fan curve
• Model VFDs and pump control to maintain a set flow rate or head/pressure

Valves

• Model relief valves and check valves
• Determine control valve capacity and insure adequate pressure drop
• Simulate pressure and flow control valves to test system interaction in the design stage
• Display effective Cv and K factor values for all valves in the system
• Identify control valve position to ensure stable valve operation

Fluid Property Models

• Built in ASME steam tables
• Optional chempak add-on with 600 gases
• Configurable interpolation models for equation of state and enthalpy
• Redlich-Kwong
• Three parameter method

Scenario Manager

• Evaluate “What-if” cases by comparing several scenarios
• Make data changes in one scenario which can be passed down to dependent scenarios
• Easily develop and switch between different operating conditions or configurations
• Evaluate new or expanding system configurations

Reporting Features

Output

• Display pipe and junction reporting sections all at once or individually
• Select output format, units and displayed items through Output Control
• Make changes to the format without re-running the analysis
• Export results to a file or copy/paste into Excel for additional reporting options
• View input and output data for multiple scenarios simultaneously

Visual Results

• Displays selected input or output parameters with your model schematic
• Vary pipe color in the model according to parameters you define based on pressure, temperature, flow and many others to see results in the context of your system
• Clearly illustrate individual lines in the context of your entire system using color mapping

Graph Results

• Graphs of flow, pressure, temperature and many other parameters are quickly and easily generated by pipe or along a flowstream
• Show compressor or fan vs. system curves
