There are charts for gas flow per pipe size and you should have the BTU's per device so you can calculate the required pipe size.

The A/C contractor told me that each device (Furnace & Tankless Water Heater) will need seperate dedicated 1" gas lines. He stated that you cannot run a single line and then T between the devices. He also stated that this actually makes it easier for them to pressure test the lines all the way from the meter to the units.
As far as line size, the A/C contractor calculated the needed gas line size based on each unit and the distance to the meter so I am assuming he accurately computed the 1" line. I will do my own calculations to confirm.
