Polytropic index for adiabatic compression
Did you know?
WebIn practice most expansion and compression processes are somewhere in between, or said to be polytropic. The polytropic process can be expressed as. pV n = constant (3a) or . p 1 … Webproving Eq.(1.10), which is the equation of state for a polytropic gas. The equation of state tells us what the pressure P is, given the density ρ and the internal heat energy e. We have seen here that upon adiabatic compression or decompression the ρ and e are related to each other. However, the precise proportionality of the relation is ...

WebThe polytropic index, n, should in theory depend on the extent of heat transfer occurring during the compression process. Limiting values for the polytropic index are unity for isothermal compression and the isentropic index for adiabatic compression.
