245. While steaming at 14.5 knots, your vessel consumes 319 barrels of fuel oil per day. In order to reduce consumption to 217 barrels of fuel oil per day, what is the maximum speed the vessel can turn for?
Fuel consumption for displacement vessels is proportional to the cube of the speed. To reduce fuel consumption from 319 to 217 barrels per day, the maximum speed is 12.8 knots.
