how do calculate the weight of gasoline lost from a 40,000L gasoline tank at 50% saturation, and 20mm hg.
To calculate the weight of gasoline lost from a tank, we need to consider the temperature, pressure, volume, and saturation level.
Here's the step-by-step process to calculate the weight of gasoline lost from a 40,000L gasoline tank:
1. Determine the density of gasoline:
- The density of gasoline can vary due to blends and additives, but for this calculation, let's assume it is 0.75 g/ml.
2. Calculate the volume of gasoline in the tank:
- The tank has a capacity of 40,000 liters, but it is only 50% saturated. So, we need to calculate the volume of the gasoline in the tank:
Volume of gasoline = 40,000 L × 0.50 = 20,000 L
3. Convert the volume of gasoline to milliliters:
- Since the density of gasoline is in grams per milliliter, we need to convert the volume from liters to milliliters:
Volume of gasoline = 20,000 L × 1000 ml/L = 20,000,000 ml
4. Calculate the weight of the gasoline:
- Now, multiply the volume of gasoline by its density to obtain the weight of the gasoline:
Weight of gasoline = 20,000,000 ml × 0.75 g/ml = 15,000,000 g
Note that the final result is in grams. To convert it to kilograms, divide by 1000:
Weight of gasoline = 15,000,000 g ÷ 1000 = 15,000 kg
Therefore, based on the given information, the weight lost from the tank would be approximately 15,000 kg at 50% saturation and 20 mmHg pressure.
