Polytropic process: formulas related to it, how you use the formulas and why they are the way they are. Heat transfer over a nite temperature difference generally causes a sigma, but heat transfer over a very small temperature difference is reversible, if q = t*ds, then it is reversible. Note: isentropic process is adiabatic (q"=0) and reversible (sigma = 0) gasses have c(p) and c(v) but solids have only c. note: all solids have the same c on a molar basis. To nd the change in entropy, delta(s), you will probably need the. Am e 2 3 0 - 3 dec 1 0. Page 2 of 3 - dec 3, 2 0 1 0. Rankine cycle choosing a different refrigerant: you want a less ideal gas,
