Question 299Steam Plants - 1st Asst/Chief70% to pass
Oil supply pressure to the main lube oil header of a gravity feed lube oil system is _______________.
AI Explanation
The correct answer is B) the result of the height of the gravity tank above the manifold.
In a gravity feed lube oil system, the oil supply pressure to the main lube oil header is determined by the height of the gravity tank above the manifold. This hydrostatic pressure, created by the weight of the oil column, is the driving force that supplies oil to the various components in the system, without the need for a service pump. The other answer choices do not accurately describe the principles of a gravity feed lube oil system.
