I currently have a natural gas pipe coming into my house with a 1" diameter. It currently terminates after about 20' and supplies a hot water heater (33,000 BTU) and a furnace (60,000 BTU).
I want to extend the run 50' to another corner of the house where it will hopefully supply a dryer, BBQ and stove.
I've been doing the sizing calculations for continuing a 1" line and it's going to be a tight fit in terms of capacity.
Since line capacity is a function of distance and pipe diameter, will I get more capacity if I increase the pipe size at the 20' mark to 1 1/4"?
