Polytropic meaning
WebInternal Energy. For an ideal gas the internal energy - u - is a function of temperature. A change in internal energy can be expressed as. du = c v dT (1) where. du = change in internal energy (kJ/kg). c v = specific heat for gas in a constant volume process (kJ/kgK). dT = change in temperature (K). Specific heat c v varies with temperature but within moderate … WebMay 30, 2024 · A polytropic process is a reversible process on any open or closed system of gas or vapor involving both heat and work transfer. The key difference between isentropic and polytropic process is that an isentropic process always shows a lower efficiency than a polytropic process. Reference: 1. Kirkby, N.F. “Polytropic Process.”

WebAnswer: I am not sure what polytropic means here. However, let me guess. Isotropic describes a process where the temperature of a system remains constant at all times. So polytropic would describe a process that changes the temperature changes over time. Adiabatic means describes a process wher... WebFeb 2, 2011 · The term "polytropic" was originally coined to describe any reversible process on any open or closed system of gas or vapor which involves both heat and work transfer, …
WebFeb 21, 2011 · The polytropic efficiency accounts for this non-ideal behavior. So I always assumed that the type of compressor was critical to determining the polytropic efficiency, since type and geometry would influence heat transfer during compression. I know this is true for some oil-bath screw compressors as they can approach isothermal performance. WebSep 19, 2011 · The key difference between adiabatic and polytropic processes is that in adiabatic processes no heat transfer occurs whereas in polytropic processes heat transfer occurs. In chemistry, we divide the …
WebWhat is the meaning of polytropic index? The polytropic index is that defined via a polytropic equation of state of the form P1+1/n, where P is pressure, is density, and n is the polytropic index. There is a relationship between the polytropic index and the adiabatic index. The latter is defined through PV=constant. WebDefinition of polytropic in the Definitions.net dictionary.

In astrophysics, a polytrope refers to a solution of the Lane–Emden equation in which the pressure depends upon the density in the form where P is pressure, ρ is density and K is a constant of proportionality. The constant n is known as the polytropic index; note however that the polytropic index has an alternative definition as with n as the exponent.

For isothermal compression, the exponent n = 1. For isentropic compression, the exponent n = k (ratio of specific heats) For compression where the isentropic efficiency is LESS than 100%, (ie: heat is added to the gas) the exponent n > k.
