When operating a system set to a magnitude of 5 psig, it's essential to understand how pressure gauges work and the implications of maximum pressure settings. The term "magnitude" typically refers to an operating parameter; in this case, it indicates 5 psig as the basis for safe operation.

In practical terms, the maximum pressure gauge reading should be designed to exceed the operating pressure to account for fluctuations and potential surges in system pressure. Operating at a magnitude of 5 psig means that the system is intended to handle pressures safely up to this level. However, to ensure safe operations and account for potential overpressure scenarios—such as system dynamics or malfunctions—maximum gauge settings are often set higher.

A common safety practice in engineering is to provide a margin above the operating pressure. Therefore, in this situation, while the system is regulated to 5 psig, the maximum pressure gauge reading typically does not exceed 10 psig, allowing for a safe buffer. This ensures that the system remains within operational limits without risking pressure-driven failures.

Setting the maximum gauge reading to 10 psig provides both safety and reliability, as it allows the pressure to fluctuate slightly above the nominal 5 psig without reaching dangerous levels. This
