A refrigerant is a substance or mixture. Usually, a fluid, used in a heat pump and refrigeration cycle that can extract heat from another body or substance. ..
The working fluid of heat engines is subjected to a series of changes (in temperature, volume, pressure, etc.), known as thermodynamic air standard cycles, through ..
The thermodynamic cycle Brayton cycle can be compared with the Otto cycle to deduce the following points: Comparison of Pressure-volume and Temperature-entropy diagrams ..
Gas Laws explain the behavior of an ideal gas in terms of temperature, pressure, volume. The following are the some of the important gas laws: Boyle’s Law Charles ..
Every substance has triple point. Triple point of a substance is a point at which it exists in solid, liquid and vapor phase. Triple point is the point of intersection ..
Liquid chillers are machines that removes heat from a liquid via a vapor-compression refrigeration cycle or vapor-absorption refrigeration cycle. This liquid can then ..
Stirling cycle is a thermodynamic cycle consists of two isothermal and two isochoric processes. Heat rejection and heat addition takes place at constant temperature. ..
The air-standard Brayton cycle is a theoretical cycle for gas turbines. This cycle consists of two reversible adiabatic or isentropic processes and two constant ..
The available energy of a system decreases as its temperature or pressure decreases and approaches equilibrium to the surroundings. When the heat is transferred ..
S.no Work Internal Energy 1 The work is the product of force and displacement in the direction of force. Internal energy is the energy stored in a substance in the form ..
In an air-cooling system, the outer surface of the cylinder and cylindrical head in reciprocating engine is cooled by air flowing over them. To increase the heat ..
The First law of thermodynamics states that energy is neither created nor destroyed, thus the total energy of the universe is a constant. However, energy can certainly ..
A Psychrometric chart can graphically represents the thermodynamic properties of air-water vapor mixture. Standard psychrometric charts are bounded by the dry-bulb ..
