in carnot cycle isothermal heating at constant pressure cannot be achieved in practice in superheated region why?but in case of raNKINE cycle it can be obtained, WHY?
Isothermal heating requires that your working fluid change phase. If the fluid is in the superheated region, it isn't changing phase, so it isn't isothermal. Adding energy to a working fluid in the superheated region results in the temperature increasing.in carnot cycle isothermal heating at constant pressure cannot be achieved in practice in superheated region why?
Adding heat in the superheated region doesn't change for any cycle. Adding heat to a superheated fluid will increase the fluid's temperature. The Rankine allows fluid to operate in this superheated region. The Carnot cycle does not. This web page shows a Carnot cycle versus a "real" cycle:but in case of raNKINE cycle it can be obtained, WHY?
Thermodynamics is the branch of physics that deals with the relationship between heat, work, temperature, and energy. It studies how these variables affect and relate to each other in physical systems, such as engines, refrigerators, and chemical reactions.
The laws of thermodynamics are fundamental principles that govern the behavior of energy in physical systems. The first law states that energy cannot be created or destroyed, only transferred or converted. The second law states that the total entropy (disorder) of a closed system always increases over time, and the third law states that the entropy of a perfect crystal at absolute zero temperature is zero.
Heat and temperature are often used interchangeably, but they are not the same thing. Heat is a form of energy that is transferred between two objects due to a temperature difference. Temperature, on the other hand, is a measure of the average kinetic energy of the particles in a substance.
Thermodynamics has many practical applications in our daily lives. It is used in the design and operation of engines, refrigerators, air conditioners, and other heat-powered devices. It is also crucial in chemical reactions, such as in the production of fertilizers and pharmaceuticals.
One common misconception is that the laws of thermodynamics only apply to closed systems, when in fact they also apply to open systems. Another misconception is that the second law of thermodynamics implies that everything in the universe is constantly getting worse and less organized, when it actually only applies to isolated systems without external energy inputs.
