What is the efficiency of a steam turbine if steam enters it with a temperature of 480 degrees

What is the efficiency of a steam turbine if steam enters it with a temperature of 480 degrees, and leaves it at a temperature of 300 degrees.

Initial data: T1 (temperature at which steam enters the turbine) = 480 K; T2 (temperature at which steam leaves the turbine) = 300 K.

The efficiency of the considered steam turbine can be determined by the formula: η = (T1 – T2) / T1.

Let’s calculate: η = (480 – 300) / 480 = 0.375 or 37.5%.

Answer: The efficiency of the considered steam turbine is 37.5%.
