What are the expansion coefficients of diesel fuel?

In summary, diesel fuel expands due to thermal expansion, with an average expansion rate of 0.1% for every 10°C increase in temperature. This can cause an increase in pressure within fuel tanks, leading to potential damage if not controlled. The limit to diesel fuel expansion is determined by its coefficient of thermal expansion, typically around 0.0008 per °C. To manage this expansion, proper fuel tank design, pressure relief valves, and monitoring of temperature and pressure are necessary.

Does anyone have the linear or cubical expansion coefficients of diesel fuel/kerosene?

Diesel fuel specific gravity (ref water @ 60°F)is pretty linear between 0 and 300°F. At 0°F, SG=.91 At 300°F, SG=.76. You can back out the expansion from that.
 

FAQ: What are the expansion coefficients of diesel fuel?

What is the expansion rate of diesel fuel?

The expansion rate of diesel fuel varies depending on its temperature and composition. On average, diesel fuel expands by about 0.1% for every 10°C increase in temperature.

What causes diesel fuel to expand?

Diesel fuel expands due to thermal expansion, which is the increase in volume of a substance as its temperature increases. As the temperature of diesel fuel increases, the molecules within it become more energized and move farther apart, causing the fuel to expand.

How does the expansion of diesel fuel affect fuel tanks?

The expansion of diesel fuel can cause an increase in pressure within fuel tanks, which can lead to bulging or even damage to the tank if it is not designed to withstand the increased pressure. This is why fuel tanks are often equipped with vents to release excess pressure.

Is there a limit to how much diesel fuel can expand?

Yes, there is a limit to how much diesel fuel can expand. This is known as the coefficient of thermal expansion, which is a measure of how much a substance expands per degree of temperature change. For diesel fuel, the coefficient of thermal expansion is typically around 0.0008 per °C.

How can the expansion of diesel fuel be managed?

The expansion of diesel fuel can be managed by using fuel tanks that are designed to withstand the increased pressure, installing pressure relief valves, and regularly monitoring the temperature and pressure of the fuel. Additionally, managing the temperature of the fuel can also help to control its expansion.
