HVAC Pipe Sizer - Liquid6.6 - App Store

The "HVAC Pipe Sizer - Liquid" application allows you to quickly size a simple pipe system by inputting a number of piping and liquid properties, including hot and chilled water (hydronic).

This app is a universal app that works on both the iPhone and iPad and adjusts its screen size accordingly.

This app now includes the HVAC Equipment Locator. Click here for details: http://bit.ly/1yTq539

You can specify the total fluid flow in GPM (or L/s) and one of either unit head loss (ft/100ft), pipe internal diameter (inches) or fluid velocity (ft/s) parameters. The results include both the exact and nominal pipe diameters and the calculated velocity and total head loss. If you are analyzing an existing pipe system, there is an option to input the existing pipe internal diameter and one of either unit head loss or fluid velocity parameters to derive the calculated fluid flow and other remaining properties.

You can specify additional parameters such as the type of liquid, various properties of the liquid, 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.

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

This application 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.

The app allows you to email inputs and results once you have completed an analysis.
