Question 613Steam Plants - Assistant Engineer

The correct answer is A) The pressure of the oil is greater than that of the cooling water. In a lube oil cooler, the pressure of the oil is typically greater than the pressure of the cooling water. This is because the oil needs to be circulated through the cooler at a higher pressure to ensure proper lubrication and distribution throughout the system. The higher pressure of the oil helps to drive it through the cooler and back to the engine, where it can continue to perform its lubricating function. The other options are incorrect because: B) Magnets are not typically installed in lube oil coolers, as they are used to remove metal particles from the oil; C) The pressure of the oil is actually greater than the cooling water, not less; and D) The temperature of the oil is typically higher than the cooling water, as the oil is absorbing heat from the engine.
