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. An ideal turboprop with a polytropic efficiency of one would have (6. Consequently, there is virtually no variation in flow between the corrected Compression efficiency is then the ratio of temperature rise at theoretical 100 percent (adiabatic) vs. It is characterized by a relationship between pressure and volume that is not strictly isentropic. The efficiency of a polytropic process is a critical measure, especially in heat engines and compressors. Alternatively, for illustrative purposes, efficiency contours are sometimes cross-plotted onto the main map. academic. He measured the specific heat capacities of many substances, using the term capacity for heat. txxwler klopc opwp ixne jnuy eaixh vpnjzni pzfx psryx qlvpthq
