MCC-NH Gas Fitters Practice Exam

Where can the formula for determining pressure change due to temperature be found?

1. Annex A 5.4

2. Annex B 7.5

3. Section 3.2 in the codebook

4. Appendix C 4.1

The correct answer is: Annex B 7.5

The formula for determining pressure change due to temperature is typically found in reference materials that are designed to provide detailed guidelines and calculations relevant to gas fitting and similar applications. In many codebooks and industry guidelines, such details would be systematically organized into sections or annexes. Annex B 7.5 is particularly relevant because it often covers operational parameters such as pressure and temperature in connection with gas systems. This annex is likely organized to provide easy access to calculations and formulas that practitioners need, such as those that evaluate the effects of temperature changes on gas pressure. In contrast, the other options may refer to less specific or unrelated guidelines. For instance, while various annexes and sections contain essential information, they might not specifically address the temperature-pressure relationship as found in Annex B 7.5, making it the most reliable reference for the formula in this context. Understanding where to find such critical formulas is essential for ensuring the safety and efficiency of gas installations.
