HVAC Pipe Sizer - Gas High

This is the only high-pressure gas piping software app I've found on the Appstore. I'm in the field a lot and this is perfect for doing quick rule-of-thumb calcs on some of the process piping that I often run across. I like that I do not have to input a value into the box, just slide the control. Great effort!

Carmel has really done a nice job designing this and other apps. So simple yet contains lots of good functionality to truly make it useful in the field and office. I'm always a little skeptical of these engineering apps because you never know how well they really work on these little iPhone screens, but sometimes simple is better. So far, the results appear to be quite accurate and even the fitting equivalent lengths for the different pipe materials look correct. I use this app a couple times a week so it's more than paid for itself.

This app is very easy to use. I simply slide the input controls, and it updates the results. For example, I can slide the gas flow control to quickly change the cubic ft/hr of gas flow to see how it affects the internal diameter and downward pressure. I can also slide the upstream pressure input slider to see how it affects results. I wish it allowed you to store info for each "pipe run" so I could build a simple pipe system to see the entire pressure loss, etc. Also, I wish you could email or upload the results somewhere so I could easily plug them into my spreadsheet. Maybe the next version. Great work, though.
