What is the recommended pressure drop for a properly functioning gas system?

0.5 psi
0.2 psi
1 psi
0 psi

The correct answer is: 0.2 psi

The recommended pressure drop for a properly functioning gas system is 0.2 psi. This specification ensures that the gas delivery system operates efficiently and safely. A pressure drop of 0.2 psi indicates just the right amount of resistance within the system, allowing for accurate measurement and reliable supply without risking significant losses in pressure that could lead to improper appliance functioning or inefficient fuel usage. This level of pressure drop allows the gas appliances to ignite and operate effectively, providing the right balance between performance and safety. If the pressure drop exceeds this threshold, it could suggest issues such as blockages, leaks, or inadequacies in the system design, which could impact overall system reliability. Therefore, maintaining the pressure drop at around 0.2 psi is critical for effective gas system operations, ensuring safety and optimal performance.
