Dulong’s formula is a mathematical equation used to estimate the Higher Calorific Value (HCV) and Lower Calorific Value (LCV) of a fuel based on its elemental composition. The formula relates the calorific values to the percentages of carbon (C), hydrogen (H), sulfur (S), and oxygen (O) present in the fuel. The equation for estimating HCV …
What is Thermodynamic Process in Gases? A thermodynamic process in gases refers to the transformation of a gas from one state to another, involving changes in temperature, pressure, volume, and internal energy. These processes are governed by the laws of thermodynamics and are essential for understanding and analyzing the behavior of gases in various physical …
What is Calorific Value of Fuel? Calorific value, also known as heating value or energy content, is a measure of the energy released during the combustion of a substance. It quantifies the amount of heat energy produced per unit of the substance. Calorific value is typically expressed in units like joules per kilogram (J/kg) or …
