Question 683Steam Plants - Assistant Engineer
70% to passLube oil cannot be efficiently filtered if it’s _______________.
Apump capacity is greater than the system's needs
Btemperature is too low
Cviscosity index is too low
Dpump discharge pressure is higher than the system pressure
AI Explanation
The correct answer is B) temperature is too low. Lube oil needs to be at the proper temperature in order to be efficiently filtered. If the temperature is too low, the oil will have a higher viscosity, making it more difficult to pass through the filter media. This can lead to increased filter clogging and reduced filter life. The other answer choices do not directly affect the ability to efficiently filter lube oil - pump capacity, viscosity index, and pump discharge pressure are not the primary factors determining filterability.
