Exam Question
A vessel of 10000 t displacement burns 25 t of fuel per day when her speed is 12 knots. Calculate the probable consumption of fuel over a voyage of 3000 nautical miles at a speed of 11 knots with a displacement of 11000 t.

Reference Answer
### Calculation of Fuel Consumption for a Voyage
This problem is solved using the Admiralty Coefficient Method or Propeller Law, which establishes the relationship between a ship's power, speed, displacement, and fuel consumption.
#### 1. Fundamental Principles
The fuel consumption of a vessel is directly proportional to the power developed by its main engine. The power, in turn, is required to overcome the ship's resistance.
