Duct sizing calculations
(OP)
Before I decide to write such a program, is there a free on line program to determine A/C pipe size for multiple separate rooms in a two story structure. Program must take into consideration such factors as room exposure to sun ,orientation and shade; window and wall sizes to the outside and inside, occupancy load (latent heat load); sensible heat from appliances and lighting; "R" factors of walls; pressure drop thru branch lines, trunk lines, risers and plenums.

What you are looking for is a complicated program invloving a heat gain/loss thermodynamic program with an optimizing fluids overlay. These programs are available, but are expensive and proprietary.
Your input is going to be much more complicated; what you have shown is inadequate.

For HVAC load calculation, you can use softwares. there are softwares given or free by suppliers and there are demo versions in the net.
Cheers!

Most of the free duct and heat-gain programs available on the net are free for a very good reason .... they are worthless........

Here my tip to you willard3, there are people who like to make mountains out of mole hills.

That's why Engineers are licensed: they recognize that what seems to be a molehill is a mountain when laymen don't.
