Why did we use Low Pressure in the first place?

• A. HP was not available at the time
• B. There wasn't enough workforce
• C. There was no need for gas at all
• D. Back then there wasn't as dense of a population and there was less demand for gas.

Answer: (D)

The main idea is that the distribution system’s operating pressure is tied to how many customers you’re serving and how far gas has to travel. In the early days, there were far fewer people and less overall demand, often spread over larger areas. With that lower demand, it was economical and safer to operate the system at a modest, low pressure. That meant simpler, cheaper pipes and regulators, and less risk from leaks and failures. That’s why the best answer points to population density and demand being smaller back then. The other reasons don’t fit as well: high pressure isn’t necessary just because gas is needed; there are transmission lines that operate at higher pressure, but the local distribution to homes could still run on low pressure. Workforce or a complete lack of need for gas aren’t the driving factors for choosing low pressure in a distribution network.
