What is specific calorific value?
Calorific value is the amount of heat energy present in food or fuel and which is determined by the complete combustion of specified quantity at constant pressure and in normal conditions. It is also called calorific power. The unit of calorific value is kilojoule per kilogram i.e. KJ/Kg.
How do you calculate the specific energy?
- 1] Specific energy (E) E=h+v22g. =1.2+1.562528×9.81. = 1.2 + 0.124. [ E = 1.324m]
- 2] Critical path (hc) hc=(q2g)1/3. =(1.87529.81)1/3. = 0.71 m.
- Critical velocity (vc) Vc=√9×hc. √9.81×0.71. [Vc = 2.639 m/s]
- 3] Minimum specific energy (E min) Emin=3hc2. = 3×0.712. [ Emin = 1.065m]
What is specific energy content?
Finally, the specific energy content of a hydrocarbon is the heat energy obtained when a certain quantity of the hydrocarbon is burned.
What is specific energy of fuel?
Specific energy is the energy per unit mass of a fuel.
What is calorific lipid value?
The calorific value of lipid is 9.0 Kcal/gm.
How do you calculate energy density?
Energy Density Calculator
- Formula. Ed = E / V.
- Total Energy (J)

What is the unit of specific energy?
joule per kilogram
The SI unit for specific energy is the joule per kilogram. Other units still in use in some contexts are the kilocalorie per gram, mostly in food-related topics, watt hours per kilogram in the field of batteries, and the Imperial unit BTU per pound, in some engineering and applied technical fields.
What is specific energy give its units?
Specific energy is an intensive property, whereas energy and mass are extensive properties. The SI unit for specific energy is the joule per kilogram.
What is the unit of specific energy consumption?
Examples of specific energy consumption (SEC) in a sentence This equates to a total specific energy consumption (SEC -a measure of the total energy consumed per unit of waste processed) by the Installation of 157 kWh/tonne for the stated waste throughput of 190,000 tpa.
What is specific energy density?
In physics, energy density is the amount of energy stored in a given system or region of space per unit volume. It may also be used for energy per unit mass, though a more accurate term for this is specific energy (or gravimetric energy density).
How calorific value is determination by bomb calorimeter?
Calorific values as determined with the bomb calorimeter represent the heat produced by a unit weight of coal when completely oxidized, when the products of the combustion are cooled to room temperature.
What is calorific value?
What is Calorific Value? VIEW MORE. Calorific Value is the parameter necessary for defining the energetic content of the materials; it is referred to as the gross calorific value (GCV) or high heating value. Also represented as the absolute value of the specific energy of combustion for a unit mass of a substance (generally, solid biofuel or food).
What is the difference between specific heat and calorific value?
Calorific value is the energy obtained by heating a substance while specific heat is the amount of heat required to raise the temperature by one unit for a unit mass of substance. Calorific value is defined as the amount of heat a unit amount of substance can release upon complete combustion.
What is the calorific value unit of fuel?
Calorific value unit is joule per kilogram or calorie per kilogram. Higher calorific value is also known as gross calorific value. (GCV) When 1 kg of fuel is burned, product of combustion is cooled down to room temperature.
How do you calculate the calorific value of food?
A food calorific value is calculated in terms of kilocalorie which is defined as the amount of energy required to raise the temperature of one litre of water by 1 degree. The energy value of food represents the value as a fuel to the body.
