How many kilograms is 50 liters of gasoline?
2 Answers
50 liters of gasoline weigh between 70 and 78 jin (Chinese pounds). The density of gasoline: 0.70~0.78g/ml. The weight of 50 liters of gasoline = density * volume = (0.70~0.78) * 50 = 35 kilograms~39 kilograms. Related introduction to gasoline: Compression ratio: The primary standard for selecting gasoline grades for cars is the engine's compression ratio, which is also the core energy-saving indicator of contemporary automobiles. The operation of an engine consists of a cyclical movement of the cylinder's "intake-compression-combustion-exhaust-intake" process. The compression ratio is the ratio of the cylinder volume when the piston is at the farthest and nearest points in its stroke. Anti-knock quality: When the piston is about 10 degrees past the top dead center, the combustion generates maximum pressure, pushing the piston with the greatest force. As the speed increases, ignition becomes increasingly advanced. Eventually, a speed is reached where the fuel-air mixture ignites before the spark occurs, which is known as knocking. The gasoline grade determines the timing of the knock point, effectively determining the engine's power output. The anti-knock performance of fuel varies with its composition. The higher the fuel's anti-knock performance, the higher the engine's compression ratio can be, improving both the engine's fuel economy and power performance.
Hey, as a car enthusiast, I often think about the weight of gasoline. For 50 liters of gasoline, the density is generally around 0.75g/cm³, so 1 liter is about 0.75 kilograms, which converts to 1.5 jin (Chinese pounds). Therefore, 50 liters would be roughly 75 jin. However, the actual weight can vary. For example, the density difference between 92 and 95 octane gasoline is about 0.01. In summer, higher temperatures can reduce the density, possibly dropping the weight to around 72 jin, while in winter, it might thicken and reach up to 78 jin. This knowledge is quite practical when refueling, helping estimate the load on the car. When going on long trips with spare fuel, it's best not to exceed the weight limit to avoid straining the car and wasting fuel. In short, it's just a rough estimate—better to play it safe and not take it as a strict rule.
