Your ship has loaded 8,000 barrels of gasoline at a cargo temperature of 36? C (97? F). API gravity is 54?. The volume correction factor (VCF) is .0006. You are bound for New Jersey from Ecuador. How many barrels would you expect to unload if the cargo temperature is 55? F at the discharge port?
• Thermal expansion/contraction of liquids and how temperature affects cargo volume • Using the Volume Correction Factor (VCF) with a temperature change to adjust the original volume • Converting between Celsius and Fahrenheit and making sure all temperatures are in the same unit system before calculating
• What is the temperature difference between loading and discharge, expressed in the same units? • How does an increase in temperature affect the volume of gasoline when using a positive VCF? • After adjusting the original 8,000 barrels for temperature change, which option is closest to your calculated result?
• Make sure you convert both temperatures into the same scale (either all °C or all °F) before finding the difference • Confirm whether the VCF is applied as VCF × ΔT × original volume or in some other way, based on your formula sheet or training materials • After calculation, check if your new volume is larger or smaller than 8,000 barrels, and eliminate choices that don’t match that trend
