Why are jet fuels generally more susceptible to water contamination than aviation gasoline?

Jet fuel being more susceptible to water contamination is primarily related to its physical and chemical properties rather than viscosity alone. Jet fuel is generally a kerosene-type fuel that can have a tendency to absorb more water over time due to its chemical makeup and the environments in which it is usually stored and used.

One factor is that jet fuel can have a higher density compared to aviation gasoline, which means it can hold onto contaminants more readily. Additionally, the presence of hydrocarbons in jet fuel, especially with lower volatility, can make it more prone to moisture being present and combining with the fuel during changes in temperature or pressure. This interaction could lead to the emulsification of water, where it becomes suspended within the fuel.

Furthermore, the properties of jet fuel, including its ability to blend with water and the conditions under which it is stored (e.g., in large tanks where condensation might occur), contribute to its susceptibility to water contamination. Thus, the correct understanding of why jet fuels are more susceptible to water contamination involves a combination of their physical properties and interaction with environmental factors.
