The simplest method to use for determining if a centrifugal pump is operating as designed is to _______________.
AI Explanation
The correct answer is B) close off the discharge valve, and watch for a rise in pressure.
The reasoning is that a centrifugal pump's performance can be easily evaluated by monitoring the pressure rise across the pump when the discharge valve is closed. This causes the pump to develop its maximum pressure, which can be compared to the pump's design specifications to determine if it is operating as intended. The other options, such as using an ammeter or observing the discharge temperature, do not directly assess the pump's pressure performance, which is the simplest and most reliable way to evaluate a centrifugal pump's operation.
