The efficiency of a steam turbine can be calculated using the formula:
η = (A / Q) * 100%, A is the value of the perfect work of the steam turbine (A = 400 MJ), Q is the amount of energy received by the steam turbine (Q = 1000 MJ).
Let’s calculate the efficiency of a steam turbine:
η = (A / Q) * 100% = (400/1000) * 100% = 0.4 * 100% = 40%.
Answer: The efficiency of a steam turbine is 40%.
