Bmechanical efficiency of the main unit
Csteam generating capacity of a vessel's boilers
Dspecific fuel consumption under steady steaming conditions
AI Explanation

The correct answer is A) values for properties of water and steam vapor at various conditions. Steam tables are used to obtain the values for properties of water and steam vapor, such as temperature, pressure, enthalpy, and density, under different conditions. This information is crucial for engineers and operators to understand the behavior of the steam system, which is essential for the efficient operation and maintenance of a vessel's steam-powered equipment. The other options are incorrect because they do not accurately describe the primary purpose of using steam tables. Option B refers to mechanical efficiency, option C refers to steam generating capacity, and option D refers to fuel consumption, which are not the main functions of steam tables.
