A polytropic process is a … WebA polytropic process is any thermodynamic process that can be expressed by the following equation: pV n = constant. The polytropic process can describe gas expansion and compression, which include heat transfer. The exponent n is known as the polytropic index, and it may take on any value from 0 to ∞, depending on the particular process. See ...
WebA polytropic process is a thermodynamic process that obeys the relation: where p is the pressure, V is volume, n is the polytropic index, and C is a constant. The polytropic process equation can describe multiple expansion and compression processes which … WebFor a polytropic process path, one in which p V n =constant along the path, n is the polytropic index. Such a process path is typically regarded as reversible, and the temperature, volume, and pressure can be varying along the path. Also, heat exchange between the system and surroundings can be occurring.
