Concerning the classification of steam turbines, a cross compound designed unit _______________.
AI Explanation
The correct answer is C) consists of a high-pressure turbine, crossover pipe, and low-pressure turbine.
A cross-compound steam turbine design consists of a high-pressure turbine, a crossover pipe, and a low-pressure turbine. This configuration allows for greater efficiency by expanding the steam across multiple stages, with the high-pressure turbine handling the initial high-pressure steam and the low-pressure turbine handling the lower-pressure exhaust steam.
The other answer choices do not accurately describe the key components of a cross-compound steam turbine design. Option A describes a Curtis-style turbine, while option B is a more general description of impulse and reaction staging, and option D refers to a reaction-style turbine with a dummy piston, which is a different configuration.
