What is engine distance?
The total revolutions of the propeller from noon to noon is obtained using the revolution counter. The engine distance can be calculated using the pitch of the propeller provided by the manufacturer.
How do I know what speed my engine is?
transmision gear * od gear * tranfercase gear * axle gear * 63360 inches/mile. The input to a standard transmission is the engine speed, expressed in revolutions per minute or RPM. Safe engine RPM in stock engines is lower than many other engines.
What is effective power of a ship?
The amount of power is determined through the concept of Effective Horsepower (EHP). Effective horsepower is defined as: “The horsepower required to move the ship’s hull at a given speed in the absence of propeller action.” Effective horsepower is often determined through model data obtained from towing tank.
What is effective engine power?
Effective Power: The Power available at the output side of the engine i.e. at crankshaft flange of the engine which connects it with the flywheel and rest of the intermediate shaft. … Effective power is determined by an engine’s size and by its mechanical efficiency.
What is the formula to calculate fuel consumption?
The following formula is used to calculate fuel consumption in litres / 100kms, the most commonly used measure of fuel consumption. (Litres used X 100) ÷ km travelled = Litres per 100km.
What is slip formula?
Slip speed is the speed difference between the Synchronous speed and Rotor speed. Slip speed = Synchronous speed – Rotor speed = Ns -N. Slip, s = (Ns – N) / Ns.
What is real slip?
Real slip or true slip
This is the difference between the theoretical speed and the speed of advance, express as a ratio or percentage of the theoretical speed. The real slip is always positive and it dependant of current.
How much fuel does an oil tanker consume?
Most ship engines have been designed for top speeds ranging between 20 and 25 knots per hour, which is between 23 and 28 miles per hour. A Panamax container ship can consume 63,000 gallons of marine fuel per day at that speed.
How are bunker prices calculated?
The BAF is calculated by multiplying the so-called ‘trade factor’ by the fuel price. The fuel price will be the same for all trades and is calculated as the average bunker price in key supply ports around the world over a period said to be “typically” three months.
