Q

Your vessel consumes 236 barrels of fuel per day at a speed of 16.5 knots. What will be the fuel consumption of your vessel at 13.0 knots?

🔍 Key Concepts

• Fuel consumption vs. speed relationships for displacement vessels • How fuel use changes when speed changes (think proportional to speed cubed for many exam problems) • Using ratios to compare old condition to new condition

💭 Think About

• How can you set up a proportion using the two speeds to find the new fuel consumption? • If fuel consumption is related to the cube of the speed, what factor do you get when you go from 16.5 knots to 13.0 knots? • Once you find that factor, how do you apply it to the original 236 barrels per day?

✅ Before You Answer

• Be sure both speeds are in the same units before using them in any ratio. • Check whether the relationship is direct or inverse with respect to speed (does consumption go up or down when speed increases?). • After calculating, compare your result with the choices and see which is closest to your computed value.
