Question 1 of 205eccefa2bacbc34ba4d47771

Referring to the table shown in the illustration, your vessel has just taken aboard 30,000 gallons of fuel with an API gravity of 35.2 at 60°F. Your vessel's specific fuel consumption at full power is 0.5 lbs. per Hp-Hr. How many hours will the fuel last if it is all burned in the 10,000 hp main engine? See illustration GS-0149.

🔍 Key Concepts

• Use the API gravity 35.2 column in the table to find pounds per U.S. gallon at 60°F. • Convert gallons of fuel to total pounds of fuel, then to total Hp-Hours available using the specific fuel consumption (0.5 lbs/Hp-Hr). • Relate total Hp-Hours to engine power (10,000 hp) to find how many hours the fuel will last.

💭 Think About

• From the table, which value do you actually need to use in your calculation: pounds per gallon or gallons per pound, and why? • Once you know how many pounds of fuel you have, how do you use the specific fuel consumption (0.5 lbs/Hp-Hr) to find the total horsepower-hours you can produce? • After you have total Hp-Hours, how do you use the 10,000 hp main engine rating to turn that into a time in hours?

✅ Before You Answer

• Be sure you select the correct row for API 35.2 and read the pounds per U.S. gallon at 60°F (not the gallons per pound). • Carefully track your units at each step: gallons → pounds → Hp-Hours → hours. • After you compute the final time, check whether the number of hours is reasonable for 30,000 gallons at 10,000 hp with 0.5 lbs/Hp-Hr (it should not be extremely small or extremely large).
