How many liters of 92 gasoline can a 25 kg barrel hold?
3 Answers
25 kg barrel can hold 25 liters of 92 gasoline, with a mass of approximately 18.475 kg. The density of water is 1000 g/cubic decimeter. 1 cubic decimeter = 1 liter, so the capacity of a 25 kg barrel is equal to 25 liters. However, the densities of water and gasoline are different. A 25 kg barrel can hold 25 liters of water, but if filled with gasoline, it would be less than 25 liters. Formula for gasoline density: The density of gasoline = 0.739 g/ml (0.739 grams/milliliter). According to the formula: mass = volume × density, the mass of gasoline is approximately 18.475 kg. Concepts of volume and capacity: Volume and capacity are not the same concept. If 25 kg of water is converted to a capacity of 25 liters (specific gravity of water is 1), the specific gravity of gasoline is 0.75, so the gasoline would only occupy 75% of the water's capacity.
When driving my own car, I pay attention to fuel consumption and fuel storage. A 25-kilogram barrel of 92-octane gasoline can hold approximately 34 liters, calculated by dividing 25 by the gasoline density of 0.73 kg per liter (25 ÷ 0.73 ≈ 34.25 liters). This accounts for the typical density range of 92-octane gasoline, which is between 0.71 and 0.77 kg per liter—I used the average. In reality, density varies with temperature: gasoline expands in hot weather, increasing volume, and contracts in cold weather, so the barrel may have more space in summer, but avoid overfilling to prevent leaks. Safe storage is crucial—use well-sealed barrels in ventilated areas, and never store them inside the car due to gasoline’s flammability and volatility. This is useful for estimating spare fuel, like a standard 50-liter car tank, equivalent to about one and a half barrels. Keep this in mind for long trips or emergency fuel planning.
I'm interested in the properties of gasoline and want to understand this issue through data. The density of 92-octane gasoline is approximately 0.73 kilograms per liter. Therefore, to calculate the volume for 25 kilograms, we divide the weight by the density: 25 divided by 0.73 equals 34.2466 liters, commonly simplified to a bit over 34 liters. There are many factors affecting density variation: batch differences and temperature influence. When hot, it can drop to 0.71, while in cold conditions, it may rise to 0.77, resulting in volume fluctuations of 1-2 liters. This conversion helps understand the logic behind gas stations selling fuel: weight is convenient for transportation calculations while volume is used for retail. This knowledge forms the basis of automotive fuel systems. Understanding it can prevent overfilling storage containers leading to spills or help determine modified fuel tank capacities. Safety advice: household gasoline containers should be kept away from fire sources to prevent explosions.
