Calculate the efficiency of a steam turbine if steam enters it at a temperature of 400 ° C and leaves it at a temperature of 60 ° C.
Task data: T1 (incoming steam temperature, heater temperature) = 400 ºС (absolute temperature T1 = 673 K); T2 (outlet steam temperature, refrigerator temperature) = 60 ºС (absolute temperature T2 = 333 K).
The efficiency of a given steam turbine is calculated by the formula: η = (T1 – T2) / T1.
Calculation: η = (673 – 333) / 673 = 0.505 or 50.5%.
Answer: A given steam turbine has an efficiency of 50.5%.
