The calorific value of diesel fuel is approximately 35 to 37 megajoules per kilogram (MJ/kg). This value can vary slightly depending on the specific composition of the diesel. In terms of calories, this translates to around 8,300 to 8,800 kilocalories per kilogram. Diesel's high energy density makes it an effective fuel for engines and machinery.
Calorific value, also known as heating value, refers to the amount of energy released when a substance is completely burned. It is typically expressed in units such as joules per kilogram (J/kg) or calories per gram (cal/g). There are two types: the higher calorific value (HCV), which includes the energy from water vapor condensation, and the lower calorific value (LCV), which does not. This measurement is crucial for evaluating the efficiency and energy content of fuels.
Calorific value is typically expressed in units of energy per unit mass or volume. Common units include joules per kilogram (J/kg), calories per gram (cal/g), and British Thermal Units per pound (BTU/lb). For gaseous fuels, it may also be expressed in megajoules per cubic meter (MJ/m³). These units indicate the amount of energy released when a specific quantity of fuel is combusted.
The weight of diesel fuel can vary slightly based on its temperature and composition, but on average, diesel weighs about 0.832 kg per liter. Therefore, 1300 liters of diesel would weigh approximately 1,081.6 kg (1300 liters x 0.832 kg/liter).
The energy value of compressed natural gas (CNG) is approximately 40-42 megajoules per kilogram (MJ/kg). This energy content can vary slightly based on the specific composition of the natural gas. CNG is often used as a cleaner alternative to gasoline and diesel in vehicles, providing efficient energy for transportation.
The better value for money is 2 kg of grapes for 3.50. With this option, you are paying 1.75 per kilogram of grapes. On the other hand, with 1 kg for 1.80, you are paying 1.80 per kilogram, which is a higher price.

The calorific value of LPG (liquefied petroleum gas) is approximately 46,000 kilocalories per kilogram.
When we are making a thermodynamic analysis of a system where diesel fuel is combusted we use the heating value of the fuel. You must determine whether you should use the higher heating value (HHV), or lower heating value (LHV), based on the application. Hope this helps.
