Web13 mei 2024 · T6 = T5 - Q /cv. where Q is the heat rejected, T is the temperature, and cv is the specific heat at constant volume, From the equation of state, we know that: p6 = p5 * (T6 /T5) where p is the pressure. The numbers indicate the two stages of the cycle. Since Q is a positive number, T6 is less than T5 and p6 is less than p5. http://teacher.pas.rochester.edu/phy121/LectureNotes/Chapter17/Chapter17.html
