How to Calculate Irreversibility?
Irreversibility calculator uses Irreversibility = (Temperature*(Entropy at point 2-Entropy at point 1)-Heat input/Input Temperature+Heat output/Output Temperature) to calculate the Irreversibility, Irreversibility of a process can also be construed as the amount of work to be done to restore the system to the original state. Irreversibility is denoted by I12 symbol.
How to calculate Irreversibility using this online calculator? To use this online calculator for Irreversibility, enter Temperature (T), Entropy at point 2 (S2), Entropy at point 1 (S1), Heat input (Qin), Input Temperature (Tin), Heat output (Qout) & Output Temperature (Tout) and hit the calculate button. Here is how the Irreversibility calculation can be explained with given input values -> 8171.548 = (86*(145-50)-200/210+300/120).
