What is the pressure drop in inches of water column supplied to a gas meter connected to a boiler room located 156 feet away?

To determine the pressure drop in inches of water column for a gas meter connected to a boiler room 156 feet away, one must consider factors such as the type of gas used, the size of the pipe, and the fittings along the way.

In this scenario, the calculation of pressure drop typically utilizes standardized equations accounting for these variables. Pressure drop occurs due to friction as gas flows through the piping system. A drop of 0.5 inches of water column suggests that the system is within acceptable limits for efficient operation.

This value also indicates a good balance between minimizing pressure loss and ensuring sufficient gas flow to the boiler. If the pressure drop were significantly higher, it could lead to performance issues or even safety concerns in gas delivery. Therefore, the choice of 0.5 inches reflects a realistic scenario within the operational standards for gas pipelines in similar installations.

The other options represent either a drop that is too low or one that could indicate an inefficient system, leading to potential operational issues. This context enhances the understanding of why a 0.5-inch drop is appropriate for a system designed to operate effectively over a distance of 156 feet.
