How do you calculate the fuel consumption of a boat?
Calculating the amount of fuel consumed.Simply enter your boat’s horsepower rating into the calculation, multiply it by the particular fuel consumption average, and divide the result by the fuel specific weight to apply the formulae to your boat.To calculate total engine horsepower in another approach, take the total engine horsepower and divide it by 10 for gas engines or by 0.06 for diesel engines.
How much fuel does a boat engine use per hour?
For example, a 150-horsepower engine will consume around 15 gallons of fuel every hour.Despite the fact that these values are averages and can vary by 10 to 20 percent, they will put you in the ballpark so you can plan a long-distance cruise without worrying about running out of petrol.Installing a fuel monitor on your yacht will also allow you to keep track of how much gasoline is being used.
How to calculate shaft power in marine engines?
The effective engine power is denoted by the letter Pe. Where n (rpm) represents the engine speed, pe = k2 + n + pe (kW or bhp). This is due to friction in the thrust bearing, which causes the shaft power to be approximately 1 percent less than the effective engine power. The computation of shaft power in marine engines may be done on ships using the information from this table.
What is the average oil consumption for two stroke diesel engines?
Engines operating at low speeds: 155 – 175 gram/kW/hour Engines operating at medium speeds: 175 – 200 gram/kW/hour Engines operating at high speeds: 195 – 225 gram/kW/hour Gas turbines: 240 – 300 gram/kW/hour (grams per kilowatt hour). Four-stroke low-speed diesel engines (test bed conditions, 42.7 MJ/kg oil) are depicted in Figure 1 as they develop specific oil consumption.
How is marine fuel consumption calculated?
What is the formula for calculating fuel consumption? You may convert miles to gallons by dividing each distance by the amount of gallons you drank throughout the journey. Combine the number of miles you went with the number of gallons of gasoline you spent from the trip odometer to get an estimate of your average fuel usage.
What is the formula to calculate fuel consumption?
The following formula is used to determine fuel consumption in litres per 100 kilometers traveled (liters per 100 kilometers traveled is the most often used metric of fuel consumption). Litres per 100 kilometers traveled = (Litres used X 100) km traveled.
How is boat consumption calculated?
- The following formula is used to estimate the maximum engine fuel consumption. Fuel Specific Weight (FSW) = (specific fuel usage x horsepower)/Gallon Per Hour (GPH).
- Example of a 300-hp diesel engine. A liter of water per minute equals (0.4×300/7.2) or 105/7.2 = 16.6 gallons per minute.
- 300-hp Example of a gasoline engine. Calculate GPH by multiplying (0.50 times 300) by 6.1, which is 150 divided by 6.1, which equals 24.5 GPH.

How is vessel fuel consumption calculated?
The following regression formula, as seen in Fig. 8, may be used to estimate the fuel consumption of the case ship based on the results of the analysis presented previously. Fuel Cons = 0.2525 x Speed2 – 1.6307 x Speed, where Fuel Cons is the fuel consumption of the main engine in gallons per day and Speed is the knots per hour of travel.
How do you calculate the specific fuel consumption of a marine diesel engine?
It is expressed as (Litres of fuel oil consumed *1000*)/(total power*1.5) and is expressed in grams per KWhr.
How is marine engine power calculated?
What is the formula for calculating the power of the Main Engine (2-stroke engine)?
- In diesel engines, a power card or a PV diagram can be used to measure the stated power output.
- Work completed in a single cycle = Mean Indicated Pressure x Area of the Piston x Length of stroke = x x
- Work completed in a single cycle =
- Pm L A N is the unit of power that has been indicated.
How is LPG consumption calculated?
Calculate Gas Cylinder Consumption by dividing total gas consumption by the product of burn rate and number of burners.
How do you calculate fuel consumption per kWh?
In order to calculate the fuel consumption, multiplying the energy output (kWh) by 0.27 will get the number of litres consumed. For a very modest diesel (under 10 kW), the figure may be closer to 0.3 litres per kilogram of electricity generated, while for an advanced, high-speed diesel (above 900 kW), the figure may be closer to 0.26 litres per kilogram of electricity generated.
How do I calculate fuel consumption per litre?
Alternatively, you may figure it out for yourself:
- Fill your tank to the brim with gas
- Reset the trip counter to zero
- Note the distance you’ve traveled when you next fill up your tank.
- Fill the tank once again and make a note of the quantity of litres that were put in
- Divide the number of miles traveled by the quantity of gasoline consumed in litres (miles per litre)
- The result is the miles per litre.
How do you calculate fuel consumption per hour?
Calculate your average speed by dividing the number of miles you went by the amount of time it took you to complete the distance. For example, if you went 200 miles in 4 hours and averaged 50 miles per hour, your speed was 200 / 4 = 50 miles per hour. Calculate how many gallons of fuel you’re burning every hour by dividing your average speed by the miles per gallon you’re getting.
How do you calculate fuel consumption from horsepower?
When written out as a formula, it looks somewhat like this:
- Given Horsepower x.50 lb fuel/hp Equals pounds of fuel for the given horsepower
- 200 pounds per hour divided by 6.25 lbs per gallon equals 32 gallons per hour.
- In the case of BSFC, 50 divided by 6.25 is 0800 gallons per horsepower per hour.
- BSFC.70 divided by 6.59 equals.106 gallons per horsepower per hour
- 800 multiplied by.106 is 84.80 gph
How do I calculate fuel consumption in Excel?
In cell E2, type the following: =C2/D2 in square brackets. To continue, press ‘Enter.’ This is the product of dividing miles traveled by gallons consumed. Your gas mileage is the consequence of this process.
How is bunker consumption calculated?
Volume (M3) equals mass (MT) divided by adjusted density. You will be able to calculate the overall volume of the bunker from this. Navigate to your sounding table and then to the page of the individual tank in which you intend to take bunker. Determine the volume by taking the trim into consideration. You will receive the final ullage or sounding of your tank at this point.
How do you calculate engine oil consumption?
Calculation of engine oil consumption using an example
- 47647 grams is equal to 916.3 x 100 x 0.52 grams. At 20 degrees Celsius, the density of 15W40 oil is approximately 0.8787 kilograms per liter. As a result, 47647 grams of oil would be equal to:
- 47647 divided by 0.8787 is 54.225 litres of oil
What is the rate of fuel consumption?
Driving a specific distance requires a certain quantity of gasoline. When measured in the United States, it is expressed as gallons per 100 miles, but in Europe and other parts of the world, it is expressed as liters per 100 kilometers.
