Gas turbine manufacturers generally state the efficiency of their turbines using LHV. However, natural gas in the U.S. is bought and sold on an HHV basis, so be careful that you don't mix units. Otherwise, you will buy a gas turbine that is too small for your anticipated needs.

What is the heating value of diesel fuel?
Lower Heating Value (LHV) MJ/kg = 43.4 Higher Heating Value (HHV) MJ/kg = 46.5
What is the heating value called when water is released in liquid phase when a fuel is burnt?
The heating value when water is released in the liquid phase during fuel combustion is called the lower heating value (LHV) or net calorific value (NCV). It considers the latent heat of vaporization released as water transitions from liquid to vapor during combustion. The LHV does not include the heat energy that would be obtained from condensing the water vapor back into liquid form.
Difference between plant heat rate and turbine heat rate?
The turbine heat rate of a steam turbogenerato is the ratio of thermal input: power generated. It is often expressed in kJ/kWh. The efficiency of the turbogenerator is simply calculated from this. The plant heat rate is the ratio of fuel energy into the plant: power generated. It is greater than the turbine heat rate, because not all of the fuel's thermal energy can be captured by the boiler, and also power station services such as fuel handling, flue gas cleaning etc consume power. Consequently, more fuel is needed for each unit of useful net power produced. Plant heat rate is often expressed in kJ/kWh or Btu/kWh. The fuel energy input used in the plant heat rate calculation may be on a higher heating value (HHV) or a lower heating value (LHV) basis, and the plant power output, although usually on a net (net of plant own consumption) is sometimes on the basis of that at the generator terminals. Whatever is used should be made clear, but it often is not.

How much Gas is required to produce 5 MW power in Gas turbine?
You must provide details of the :- 1) Inlet air temperature 2) Fuel characteristic (LHV, sulphur contents, etc.) 3) Site elevation 4) Inlet / Exhaust loss 5) Open cycle type of GT ? Heat Recovery ? Then the supplier will calculate for you.

What is the calorific value of diesel fuel?
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.
How many liters are in one gallon of diesel?
this number is going to be all over the place, but to find an average, the technical name for the quantity you are looking for is called the Lower Heating Value or LHV. Google it, and you will quickly find an average. I found 45 MJ/kg to be reasonable. LHV is the number used in combustion engines of all kinds, jet, diesel, gasoline...
How many kilojole per hr in 62.7 kilomol per hr of natural gas?
To calculate the energy content of natural gas in kJ/hr, you need to know the lower heating value (LHV) of natural gas. Once you have the LHV, you can multiply the amount of natural gas in kilomol/hr by the LHV to get the energy content in kJ/hr.
What is the lower heating value of hydrogen sulfide?
The lower heating value of hydrogen sulfide (H2S) is around 14,700 BTU/lb. This value represents the amount of heat released when one pound of H2S is burned completely in oxygen at constant pressure with the products cooled to 150 degrees Fahrenheit.
