Core TradesCâu 30 / 700
When sizing fuel-gas piping to appliances, the two governing factors are the total gas demand (Btu/hr) and:
a.The color of the pipe coating
b.The ambient room temperature
c.The developed (longest) length of the piping run
d.The number of shutoff valves installed
Giải thích
Gas pipe is sized from a table using the total connected demand and the developed length to the farthest appliance, which together set the required diameter. Coating color, room temperature, and valve count do not govern the pipe size.
