Pressure relief is a vital part of safe process design, and assessing the capacity of relief streams & sizing associated equipment is an important part of this.

VisualAdrian calculates flows and pressures for high velocity, compressible gases allowing you to:-

• Model flow in a single pipe or a network of pipes;
• Predict precisely where choking occurs;
• Model a system in which different gases mix at different locations;
• Consider adiabatic & isothermal conditions;
• Calculate the flow through a variety of pipe sizes & fittings such as bends, relief valves, bursting discs;
• Summarise key results to see rapidly in detail what is happening within any pipe.

The piping system is drawn with Microsoft Visio using a specially designed template for inserting fittings into pipes in the correct orientation.

There are purpose-built forms for adding the process data with full units conversion, Physical Property calculators, pipe inner diameter calculators, and roughness calculators. Changes in diameter and roughness are propagated up and down the pipe where appropriate.

Results are displayed in an easy-to-read format highlighting any chokes that occur with a calculator for determining pressure drops upstream and downstream of a relief valve. Tailor-made reports are generated using Microsoft Word giving a complete record of the calculation input and output specific to your own requirements.
