When the calorific value of fuel increases does the efficiency of fuel go up or down?

=> When the calorific value of a fuel increase, the efficiency of the fuel go up.. so, if C.V. increase then heat produced by fuel on combusion per unit volume will increase…

How is calorific value related to efficiency of fuel?

The efficiency of fuel of food is dependent on the calorific value; higher the value, higher the efficiency, and similarly lower the calorific value, lower is the efficiency. Therefore, it can be said that the calorific value of a substance is directly related to or proportional to its efficiency.

What does high calorific value mean?

The higher heating value (also known gross calorific value or gross energy) of a fuel is defined as the amount of heat released by a specified quantity (initially at 25°C) once it is combusted and the products have returned to a temperature of 25°C, which takes into account the latent heat of vaporization of water in …

What is meant by calorific value of a fuel?

Definition of calorific value : the heat produced by the combustion of a unit weight of a fuel.

Which fuel is having highest calorific value?

hydrogen
Calorific value is nothing but the energy contained in a fuel or food, determined by measuring the heat produced by the complete combustion of a specified quantity of it. This is now usually expressed in joules per kilogram. Hence, hydrogen has the highest calorific value.

What is calorific value of a fuel define gross calorific value and net calorific value of a fuel and write down the relation between them?

Net Calorific Value & Gross Calorific Value So the gross calorific value indicates how much energy can be released during the complete combustion of a given amount of fuel: It is comprised of the net calorific value plus the energy contained in the exhaust gases and in the water vapor produced during combustion.

What is the difference between fuel efficiency and calorific value?

Fuel efficiency is measured as the amount of heat that 1 kg of fuel (any fuel) produces on combustion. This is known as the calorific value of the fuel. The unit of measurement of fuel efficiency is kilojoules per kg, i.e. kJ/kg.

Which fuel has higher calorific value among given fuels?

8. Which fuel has higher calorific value among given fuels? Explanation: Gasoline also called as petrol, has the highest calorific value. Gasoline is a transparent petroleum derived liquid that is used primarily as a fuel in internal combustion engines.

Does the calorific value of gas change?

The reason the Conversion Factor changes is that the energy content of your gas (sometimes referred to as its calorific value) varies depending on: Where it is sourced from. The physical composition of the gas. Local temperature and pressure.

Which term is used to express the efficiency of a fuel?

Calorific value
Calorific value is used to express the efficiency of fuel.
