Question 1 of 2066636ee728f7522a1c5188cd

Your ship departed Venezuela for New York, loaded with 10,000 barrels of crude oil, whose average cargo temperature was 30? C (86? F). API is 25?. The volume correction factor (VCF) is .00045. If this cargo is heated to 100? F prior to discharge, how many barrels will you offload?

🔍 Key Concepts

• Thermal expansion of liquids – what happens to oil volume when temperature increases? • How to use a Volume Correction Factor (VCF) when temperature changes from one value to another • The relationship: corrected volume = original volume × [1 ± (VCF × ΔT)]

💭 Think About

• Start by finding the temperature change between loading (86°F) and discharge (100°F). Is ΔT positive or negative? • Should the corrected volume be greater than or less than 10,000 barrels when the temperature is higher? Eliminate choices that don’t match this logic. • Plug your ΔT and VCF into a simple expansion/contraction form: original volume × [1 + (VCF × ΔT)]. Which option is closest to that result?

✅ Before You Answer

• Be sure you are using degrees Fahrenheit for ΔT, since both given temperatures are in °F. • Confirm that you’re applying the VCF per degree to the temperature difference (ΔT), not to the absolute temperature. • Double-check whether API gravity is actually needed here, or if it’s just background information once the VCF is already given.
