How does temperature affect fuel handling?

Temperature plays a critical role in fuel handling, particularly because it affects both the viscosity and vapor pressure of the fuel. Viscosity refers to the thickness or flowability of a liquid. As the temperature of a fuel increases, its viscosity typically decreases, making it easier to pump and handle. Conversely, lower temperatures can lead to increased viscosity, potentially causing challenges in fuel transfer and equipment performance.

Vapor pressure is another important characteristic influenced by temperature. It is the pressure exerted by the vapor phase of a liquid in equilibrium with its liquid phase. Higher temperatures lead to increased vapor pressure, which can result in evaporation losses during handling and storage, as well as an increased risk of flammable vapors being released into the environment. This can raise safety concerns and necessitate additional precautions during fuel transfer and storage processes.

Understanding these relationships is crucial for effective fuel management, as they help guide operational practices to ensure safety, efficiency, and compliance with regulations.
