What is the efficiency of a heat engine if the work per cycle is 100 J, the heat received from heating is 160 J?
| August 12, 2021 | education
These tasks: A (work of the used heat engine per cycle) = 100 J; Qн (heat received by the heater) = 160 J.
The efficiency of the used heat machine is calculated by the formula: η = (Qn – Qx) / Qn = (Qn – (Qn – A)) / Qn = A / Qn.
Let’s calculate: η = 100/160 = 0.625 (62.5%).
Answer: The efficiency of the used heat engine is 62.5%.
