What is the criteria to decide the efficiency of fuel?

Vehicle fuel efficiency This is known as Brake Specific Fuel Consumption (BSFC) and is determined by the rate of fuel consumption divided by the power produced, expressed as grams per kilowatt-hour and is a measure of the engines fuel efficiency.

What is a good litre per km?

In general, 5 to 8 litres per 100 km would be considered a good fuel efficiency, 8 to 12 litres per 100 km would be average, and more than 12 litres per 100 km would be considered a relatively low fuel efficiency. Your driving habits also impact how efficiently your vehicle will use its fuel.

How do you calculate mass of fuel consumption?

Gathering all the terms together, TSFC is the mass of fuel burned by an engine in one hour divided by the thrust that the engine produces. The units of this efficiency factor are mass per time divided by force (in English units, pounds mass per hour per pound; in metric units, kilograms per hour per Newton).

What is the unit of measurement for fuel consumption?

The three standard units of fuel consumption are the liter of petroleum per 100 kilometers, the mile per gallon of petroleum, and the kilometer per liter of petroleum.

Is 8.9 Litres per 100km good?

In general, 5 to 8 litres per 100 km would be considered a good fuel efficiency, 8 to 12 litres per 100 km would be average, and more than 12 litres per 100 km would be considered a relatively low fuel efficiency.

What is the density of 1 cubic meter of gasoline?

Gasoline weighs 0.7489 gram per cubic centimeter or 748.9 kilogram per cubic meter, i.e. density of gasoline is equal to 748.9 kg/m³. In Imperial or US customary measurement system, the density is equal to 46.75 pound per cubic foot [lb/ft³], or 0.4329 ounce per cubic inch [oz/inch³] .

What is the energy density of gasoline in spring 2001?

Spring 2001. Energy density is the amount of energy stored in a given system or region of space per unit volume or mass. It therefore has units of energy per length cubed or energy per mass. Gasoline has an energy density of about 45 megajoules per kilogram (MJ/kg).

Why does gasoline have a higher density than water?

Gasoline with higher densities have a higher content of aromatics, mostly chemical compounds that are derivatives of benzene. Gasoline floats on water which means that water has a higher density than gasoline. If the two compounds are put together in a container, gasoline will float, as the two do not mix and because gasoline is lighter.

What is the specific gravity of a gallon of gasoline?

The specific gravity of gasoline is from 0.71 to 0.77, with higher densities having a greater volume of aromatics. Finished marketable gasoline is traded (in Europe) with a standard reference of 0.755 kg/L (6.30 lb/US gal), and its price is escalated or de-escalated according to its actual density.
