Turbine lube oil suction strainer baskets have _______________.
AI Explanation
The correct answer is B) coarse perforations.
Turbine lube oil suction strainer baskets typically have coarse perforations, not fine perforations, to capture larger debris and protect the turbine bearings and other components from damage. The coarse perforations allow sufficient flow of the lube oil while filtering out larger particles that could cause mechanical issues. The other answer choices, such as a wire cloth frame or self-cleaning design, are not the standard configuration for turbine lube oil suction strainers.
