A single gas main serves a 40,000 BTU/hr water heater, a 100,000 BTU/hr furnace, and a 65,000 BTU/hr range. What total connected load must the main be sized to carry?
a.100,000 BTU/hr
b.165,000 BTU/hr
c.205,000 BTU/hr
d.40,000 BTU/hr
Giải thích
The section feeding all three appliances must carry the sum of their inputs: 40,000 plus 100,000 plus 65,000 equals 205,000 BTU/hr. Convert to cfh (about 205 cfh for natural gas) and size that section for the full connected load. Individual branches downstream only carry the demand beyond that point.
