Question 1 of 205eccef9cbacbc34ba4d45bf6

A fuel tank on your vessel is 20 feet high, 20 feet long and 20 feet wide. If it is filled 100% with fuel having an API gravity of 35.7 at a temperature of 60°F, how many long tons of fuel are in the tank? See illustration GS-0149.

🔍 Key Concepts

• Use the tank dimensions (20 ft × 20 ft × 20 ft) to find cubic feet, then convert cubic feet to U.S. gallons (use 7.48 gal/ft³). • From Table GS-0149, use the API gravity 35.7 at 60°F to find pounds per U.S. gallon, then multiply by total gallons to get total pounds. • Convert total pounds of fuel to long tons (remember: 1 long ton = 2,240 lb).

💭 Think About

• What is the total volume of the tank in cubic feet, and how do you convert that volume into U.S. gallons? • Looking at the 35.7 API column in the table, what is the correct value for pounds per U.S. gallon at 60°F, and how does that affect the total weight? • Once you have total pounds, how do you convert that to long tons, and which choice is closest to your computed result?

✅ Before You Answer

• Be sure you are reading pounds per U.S. gallon (not gallons per pound) for 35.7 API at 60°F from the correct column. • Confirm you are using the correct conversion: 1 ft³ = 7.48 U.S. gallons and 1 long ton = 2,240 lb. • After you compute the long tons, compare it with the answer choices and check that your result is reasonable for an 8,000 ft³ tank of fuel (expect a value on the order of hundreds of long tons, not tens).
