Anyone recommend a duct work calculator app? Download, online, Android, cheap or free?
I've been all over the internet, I can figure out the tonnage and BTUs needed, I can calculate CFM needed for each room. I can calculate how many CFM a given size duct can support over a given length.
I can't find anything that allows for adding branches.
I'm working with a limited space and need to figure out if I can get sufficient airflow to my various rooms. I've seen some online calculators, but nothing like what I'm looking for. I'd like to be able to put in my available CFM or tonnage, with X diameter, X length, X number of branches, that are X diameter, and X length, and find out what the CFM at each register is. Knowing when to step down in size on the length of the run would be handy too.
Anyone DIY HVAC and have any tips? I'm not opposed to paying subbing out our HVAC work, but I need to figure out what I'm wanting to do is even feasible.
Anyone have experience with high velocity HVAC systems? I can use a lot smaller duct work with those.
