Hydrostatic expansion of ammonia increases pressure by how much per degree of Fahrenheit heat exposure?

The correct answer indicates that hydrostatic expansion of ammonia can significantly increase pressure, with an increase ranging from 100 to 150 PSI per degree Fahrenheit of heat exposure. This is a critical concept in the context of ammonia handling and storage, as it highlights the importance of monitoring temperature and pressure closely.

Ammonia, as a refrigerant, exhibits particular thermal properties that lead to substantial pressure increases when subjected to heat. The specific range presented in the correct answer reflects the need for careful management of ammonia systems to prevent dangerous pressure build-ups, which can occur due to thermal expansion. This understanding is vital for operators to ensure safe handling of ammonia under varying temperature conditions.

In practice, knowing that the pressure can increase so significantly with even a slight rise in temperature underscores the necessity of having appropriate safety measures in place, such as pressure relief valves and proper insulation, to mitigate risks associated with thermal expansion.
