How much does a 10% mixture of JP-4 in JP-5 reduce the flash point by?

• A. 60°F
• B. 70°F
• C. 80°F
• D. 90°F

Answer: (C)

A 10% mixture of JP-4 in JP-5 results in a substantial reduction of the flash point due to the inherent properties of the two fuels. JP-4 has a significantly lower flash point compared to JP-5, meaning it ignites more easily at lower temperatures. When mixed, the more volatile JP-4 lowers the overall flash point of the combined mixture. By understanding the specific properties of these fuels, it can be confirmed that the correct reduction in flash point from this specific mixture is 80°F. This is particularly critical in aviation operations, where understanding fuel properties ensures safe handling and storage practices. The significant decrease in flash point emphasizes the need for careful consideration and protocol adherence when dealing with fuel mixtures to mitigate fire hazards.
