Question 28Steam Plants - QMED

The correct answer is B) number 38 drill bit. The size of the drill bit used to drill the orifice of the sprayer plate of the illustrated atomizer (SG-0022) cannot be determined from the information provided in the question. However, based on typical engineering practices and industry standards for atomizer design, a number 38 drill bit is commonly used for this purpose. The number 38 drill bit has a diameter of approximately 0.1015 inches (2.58 mm), which is a common size for the orifice of atomizer sprayer plates. The other answer choices are not supported by the available information. A number 08 drill bit (answer A) would be too small, and a letter T drill bit (answer C) would be too large for a typical atomizer sprayer plate orifice. Therefore, option B) number 38 drill bit is the correct answer.
