## What is HVAC Pipe Sizer?

The "HVAC Pipe Sizer - Steam" application allows you to quickly size a simple steam pipe system by inputting a number of piping and steam properties.

This app is now 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/1BPl1Nr

It also includes a bonus steam table calculator that allows you to specify 2 parameters for either saturated or superheated steam and display the remaining steam properties.
 
In the pipe sizing module, you can specify the total steam flow in lbs/hr (or kgs/hr), the initial steam pressure (psia or psig) and one of either pressure loss (psi/100ft), pipe internal diameter (inches) or steam velocity (ft/s) parameters. The results include both the exact and nominal pipe diameters and the calculated velocity and total pressure loss. If you are analyzing an existing steam pipe system, there is an option to input the existing pipe internal diameter, initial steam pressure and one of either pressure loss or steam velocity parameters to derive the calculated steam flow and other remaining properties.

You can specify additional parameters such as whether the steam is saturated or superheated (with accompanying temperature), 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.

The bonus steam table module is one-of-a-kind. It allows you to easily view results by selecting a variety of input parameters and easily altering these inputs using the slider control. This is perfect for students who often rely upon the more static printed steam tables in engineering text.

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.

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

### 1/5 — Junk

*2016-03-10*

Only included the pipe sizer app, no steam tables. Downloaded twice, not worth the money.

### 5/5 — Great for my son's thermo classes

*2010-01-04*

I still remember like it was yesterday that I had to manual interpolate all of those steam properties from the steam tables in my thermodynamic books.

Now, my son is studying thermo, and he's able to use this app to automatically interpolate for different types of steam properties. Very useful.

Also, I like the steam pipe sizing capabilities that are included: it's like having 2 apps in one. Good job Carmel.

### 5/5 — Love the steam table capabilities

*2009-11-06*

I really like the steam table functionality in the app. I can select any combination of 2 parameters and it will calculate the remaining steam properties. It's so much better than looking it up in my steam table books. Great work!
