Isentropic Process Isentropic means constant entropy. A process during which the entropy remains constant is called an isentropic process, which is characterized by ΔS = 0 Or S₁ = S₂ for a process 1 – 2. If a process is both reversible and adiabatic, then it is an isentropic process. An isentropic process is an Read more about Isentropic Process[…]
Isobaric Process An Isobaric Process is a thermodynamic process, in which the pressure of the system remains constant (P = Constant). The heat transfer into or out of the system does work, but also changes the internal energy of the system. Since there are changes in internal energy (dU) and changes in system volume (ΔV) engineers Read more about Isobaric Process[…]
Isochoric Process An Isochoric process is a thermodynamic process in which the volume remains constant. Since the volume is constant, the system does no work (W = 0). It is also called as constant volume process, and Iso – Volumetric process or an isometric process is a thermodynamic process during which the volume of the closed Read more about Isochoric Process[…]
Cyclic Process What is cyclic process? A process in which a system goes from an initial state to a final state and returns back to the initial state is called a cyclic process. The net energy change in a cyclic process is zero. That means, in a cyclic process, the system starts and returns to the Read more about Cyclic Process[…]
Adiabatic Process Adiabatic process is a thermodynamic process in which there is no heat (Q = 0) transfer into or out of a system and is generally obtained by surrounding the entire system with a strongly insulating material or by carrying out the process so quickly that there is no time for a significant heat transfer to take place. Read more about Adiabatic Process[…]
Measurement of Mass Mass as a physical property of a body. Mass is a measure which helps in analysing how strong is a mutual attraction between two bodies. It is generally a wrong belief that mass is same as weight, as mass is a constant quantity, whereas weight is a variable quantity. Mass: Mass is a basic characteristic of matter. Read more about Measurement of Mass[…]
Isothermal Process When a thermodynamics system undergoes a physical change in such a way that its temperature remains constant, then the change is known as isothermal changes. What is Isothermal Process? When a gas undergoes expansion or compression at constant temperature, the process is called isothermal process. This process is basically a thermodynamic process. Usually there Read more about Isothermal Process[…]
Potentiometer The potentiometer is an electric instrument that used to measure to Electro Motive Force of a given cell, the internal resistance of a cell and also it is used to compare MFs of different cells. It can also use as a resistor in most of the applications. These potentiometers are used in huge quantities in Read more about Potentiometer[…]
Thermodynamics What is Thermodynamics? Thermodynamics is the sub-division of science that deals with the study of the combined effects of heat and work with changes in state confined by the laws of thermodynamics. Heat energy associated with chemical reactions is converted into different usable forms based on the laws of thermodynamics. The fact that energy can never Read more about Thermodynamics[…]
Applications of Bernoulli’s Theorem According to Bernoulli’s theorem, whenever there is an increase in the speed of the liquid, there is a simultaneous decrease in the potential energy of the fluid and also we can say that there is a decrease in the pressure of the fluid. Basically, it is principle of conservation of energy Read more about Applications of Bernoulli’s Theorem[…]
