Question 1 of 2066636ee728f7522a1c5188df

Your ship has loaded 8,000 barrels of gasoline at a cargo temperature of 85? F, departing Aruba bound for New Jersey. API gravity is 55?. The volume correction factor (VCF) is .0006. How many barrels would you expect to unload if the cargo temperature is 50? F at the discharge port?

🔍 Key Concepts

• Thermal expansion/contraction of liquids – how volume changes when temperature changes • Using volume correction factor (VCF) with a temperature difference (ΔT) to adjust loaded volume • Relating initial volume, temperature change, and VCF to find the expected discharge volume

💭 Think About

• First, determine the temperature difference between loading and discharging. Is the cargo getting warmer or cooler? How does that affect volume? • Think about how to apply the VCF with the temperature change: should you add or subtract the volume change from the original 8,000 barrels? • After you compute the corrected volume, compare it logically: should the final volume be more, less, or about the same as 8,000 barrels, given the temperature change?

✅ Before You Answer

• Calculate ΔT (change in temperature) correctly, including the sign (positive or negative) • Apply the formula using VCF × ΔT × original volume to find the change in volume, then adjust the original 8,000 barrels appropriately • Check that your final answer makes physical sense: colder gasoline should have a smaller volume, so the expected discharge quantity should reflect that
