In gas distribution, what determines the specific service pressure needed at customers' service connections?

The specific service pressure needed at customers' service connections is determined by the demand of the customers. This demand refers to the amount of gas that the customers are expected to use, which can vary based on factors such as the appliances they operate and their consumption patterns. Higher demand typically necessitates a higher pressure to ensure that an adequate and consistent supply of gas is delivered to meet the needs of the consumers.

While factors such as the type of gas used, the configuration of the network, and the length of service lines can influence the overall design and efficiency of the gas distribution system, they do not primarily dictate the service pressure required at individual service connections. The service pressure must be sufficient to cater effectively to customer demand, ensuring reliability and safety in gas supply.
