How many liters of gasoline can a 25-liter barrel hold?

[McPhoebe]

So a 25-kilogram plastic barrel can hold 33.3333 liters of 93-octane gasoline. It can hold 29.7619 liters of diesel. Characteristics of gasoline: 1. Evaporation: Refers to the ease with which gasoline evaporates in the carburetor. It has an important impact on engine starting, warm-up, acceleration, vapor lock, fuel consumption, etc. The evaporation of gasoline is comprehensively evaluated by three indicators: distillation range, vapor pressure, and gas-liquid ratio. 2. Anti-knock: Refers to the ability of gasoline to resist detonation combustion under various operating conditions. The anti-knock of automotive gasoline is expressed by the octane number. The higher the octane number, the better the anti-knock performance. The anti-knock capacity of gasoline is related to its chemical composition. Branched-chain alkanes, olefins, and aromatics usually have excellent anti-knock properties. 3. Stability: Refers to the stability of gasoline when stored for a long time under natural conditions. It is characterized by gum content, induction period, and iodine value. The lower the gum content, the better; the longer the induction period, the better. National standards stipulate that the actual gum content per 100 milliliters of gasoline must not exceed 5 milligrams. The iodine value indicates the content of olefins. 4. Corrosiveness: Corrosiveness refers to the characteristic of gasoline to corrode storage tanks, pipelines, valves, carburetors, cylinders, and other equipment during storage, transportation, and use. It is characterized by total sulfur, mercaptan, copper strip test, and acid value. 5. Safety: The main safety performance indicator of gasoline is the flash point. The national standard strictly stipulates a flash point value of ≥55°C. If the flash point is too low, it indicates that the gasoline contains light components, which poses safety hazards during storage, transportation, and use, and can also prevent the car engine from working properly.

I often use a 25-liter can to buy gasoline. This can is designed to hold 25 liters of liquid, and gasoline is no exception—it can hold 25 liters. However, gasoline expands when heated and contracts when cooled. On hot days, as the temperature rises, the gasoline may expand and overflow, posing a potential hazard. It is recommended to fill it to about 24.5 liters, leaving some space. The nominal capacity of the can is a fixed standard, and as long as no pressure is applied, it remains safe. At the gas station, I carefully fill it up to near the can's opening, ensuring not to exceed the limit, and then seal the lid properly. This method is convenient for storage and helps prevent evaporation issues.
