Engineers testing the efficiency of an electric generator gradually vary the temperature of the hot steam used
Question:
Engineers testing the efficiency of an electric generator gradually vary the temperature of the hot steam used to power it while leaving the temperature of the cooling water at a constant 20°C.
They find that the generator’s efficiency increases at a rate of 3.5 × 10-4 K-1 at steam temperatures near 300°C. What is the ratio of the generator’s efficiency to the efficiency of a Carnot engine?
