Final answer:
The normal natural gas building line pressure for a single-family residence typically ranges from 7 inches of Water Column (approximately 0.248 psi) to about 0.5 psi.
Step-by-step explanation:
The question you're asking about pertains to the normal building line pressure for natural gas in a single-family residence. While this question mentions examples about water and oil pressure, this might be confusing, as these are different scenarios and do not directly relate to natural gas line pressures. To give you an accurate answer; the typical residential natural gas line pressure is low, usually ranging from 7 inches of Water Column (approximately 0.248 psi or 1.71 kPa) to slightly higher pressures around 0.5 psi or 3.45 kPa. Different regions and utility companies may have slight variations, but this is a general guide for typical home appliances.
