Carnot Efficiency Calculator (η=1−Tc/Th)
Compute the maximum efficiency of an ideal Carnot engine operating between hot reservoir Th and cold reservoir Tc, plus the Carnot refrigerator / heat pump coefficients.
Key points
Carnot Efficiency Calculator (η=1−Tc/Th): Compute the maximum efficiency of an ideal Carnot engine operating between hot reservoir Th and cold reservoir Tc, plus the Carnot refrigerator / heat pump coefficients. Formula: η = 1 − Tc/Th (absolute temperature K). Enter parameters on the DD-CAT IDE online tool page to get results instantly, with a calculation-model diagram that updates with the inputs. Carnot efficiency η = 1 − Tc/Th is the theoretical maximum for any engine between two reservoirs; temperatures must be in kelvin. Ways to raise engine efficiency: increase the hot reservoir temperature Th or lower the cold reservoir temperature Tc.
