Final answer:
The correct option is: D) low fuel load. A computational fire model would NOT be required when the condition of low fuel load is present In such cases, the mass flow can be estimated using simpler analytical methods without the need for a computational fire model.
Step-by-step explanation:
In the context of determining the mass flow through an opening, a computational fire model would NOT be required when the condition of low fuel load is present. A low fuel load means that there isn't much material available for combustion, resulting in a minimal amount of heat and fire. In such cases, the mass flow can be estimated using simpler analytical methods without the need for a computational fire model.
