Q

Your vessel consumes 199 barrels of fuel per day at a speed of 14.5 knots. What will be the fuel consumption of your vessel at 10.0 knots?

🔍 Key Concepts

• Relationship between speed and fuel consumption for a displacement vessel (roughly proportional to the cube of speed) • Setting up a ratio using known fuel use at one speed to estimate use at another • Careful unit consistency (barrels per day, knots) when doing proportional calculations

💭 Think About

• How does fuel consumption change when speed is reduced: does it go up or down, and by a little or a lot? • If fuel use is roughly proportional to the cube of speed, what expression could you write that includes 199 bbl/day, 14.5 knots, and 10.0 knots? • Once you compute the new fuel consumption, which choice is closest to your calculated value?

✅ Before You Answer

• Write a clear formula before calculating: e.g., fuel2 ≈ fuel1 × (speed2 / speed1)^3 • Double-check the direction of change: slower speed must give lower fuel consumption per day, not higher • Recalculate at least once to avoid calculator/rounding errors and ensure your result is near one of the options
