HVAC Pipe Sizer - Gas High

Performs high pressure gas pipe sizing

The HVAC Pipe Sizer - Gas High application allows you to quickly size a simple high pressure (> 1.5psi) gas piping system by inputting a number of piping and gas properties.

You can specify the total gas flow in ft^3/hr (m^3/hr), the upstream pressure (psig or kPa), and one of either downstream pressure (psig or kPa), pipe internal diameter (inches) or gas velocity (ft/s) parameters. The results include both the exact and nominal pipe diameters and the calculated velocity and total pipe equivalent length. If you are analyzing an existing pipe system, there is an option to input the existing pipe internal diameter, the upstream pressure, and one of either downtream pressure or gas velocity parameters to derive the calculated gas flow and other remaining properties.

You can specify additional parameters such as the type of gas, various properties of the gas, the pipe material type, the total length of pipe, quantities for up to 11 different types of pipe fittings, and much more. You can also choose to display values in either english or metric units.

It also includes built-in pipe fitting equivalent length and nominal pipe sizing tables for a wide variety of pipe material types and diameters.

It uses slider controls that allow you to quickly increment or decrement the input values and immediately observe the calculated results. You can also manually input exact values.

Finally, you can email inputs and results to yourself for further analysis on a desktop computer.

This application was designed by Carmel Software Corporation, a leader in HVAC design software since 1995. In fact, Autodesk (the makers of AutoCAD) acquired our load calculation software and incorporated it into their leading 3D modeling software called Revit.
