The temperature is heated by the heat engine 600 K and the temperature of the refrigerator is 250 K. Find the efficiency of the machine.
To find the efficiency of the applied heat engine, we will use the formula: η = 1 – Тх / Тн.
Values of variables: Тх – machine refrigerator temperature (Тх = 250 К); Тн – machine heater temperature (Тн = 600 К).
Let’s calculate: η = 1 – 250/600 = 0.583 (3) or 58.3 (3)%.
Answer: The efficiency of the applied heat engine, according to the calculation, is 58.3%.
