In LIQTHERM v7.0, the pipeline model may be created graphically using a drag and drop approach.

• In this method, objects such as pipe segments, valves, tanks, pump stations and other devices may be selected from a toolbox and dropped on a drawing canvas.
• These objects can be connected with pipe segments to form the pipeline system.
• The properties of each object may be defined by double-clicking on them and entering data in the screen that is displayed.

LIQSURGE program for surge analysis or transient analysis of pipelines transporting liquids.

In GASMOD v7.0, the pipeline model may be created graphically using a drag and drop approach.

• In this method, objects such as pipe segments, valves, tanks, compressor stations and other devices may be selected from a toolbox and dropped on a drawing canvas.
• These objects can be connected with pipe segments to form the pipeline system. The properties of each object may be defined by double-clicking on them and entering data in the screen that is displayed.

PUMPCALC is a Centrifugal Pump Analysis Program

It can be used to predict the performance of one or more centrifugal pumps, at various impeller sizes, speeds and series or parallel configurations.

The following are the main features of PUMPCALC:

• Single pump performance- Impeller size and speed changes
• Multiple Pump Performance – Series and Parallel Configuration
• Viscosity Corrected Pump Performance – Hydraulic Institute method.
• Pump Head Curve versus Pipe System Head Curve- Operating point
