Update looks good.
Nice update. I like the new aspect ratio slider control.
Residential
Smaller increments would do great, 90% of hvac is residential and we need people to know how to size duct correctly!
Not a great interface.
The interface should be completely rethought. My old Ductulator is so much easier to use. I hope they improve the user input in future versions or I may have to write a ductulator app myself.
Very usefull app
I just gota say very cool app
Foreman
Its Grrrreat! I wish this Application had a mode for lower numbers like 1 to 2000 cfm for Easy field Calculations and a QUICK rectangle to round converter. I like this App. and use it daily!
Room for improvement
It's a little fiddly. And some obvious featues are missing.
User request to be able to set the Pa/30m as a constant when in duct dimension mode.
Pressure drop rates would be good in Pa/m, not just Pa/30m (who uses that!).
Add option for user to input a K factor for a fitting and return fitting pressure drop.
User selectable list for standard small duct sizes (ie 100mm, 150mm, 200mm, 250mm, etc). Duct aspect ratio being fixed unless changed in the settings page is very annoying.
Oh, and metric units for duct dimensions should be in mm, not cm.
Could be a neat app, but unfortunately my equivalent excel spreadsheet is much easier to use.

Good, solid duct sizing program
This is a good, solid duct sizing program for sizing a few duct runs in the field. I have used it on recent occasions, and found it to be great. I no longer have to carry a ductulator with me.
