Why does the outlet pressure gauge show an increase when the flow rate of the centrifugal pump decreases? And why does the outlet pressure drop during evacuation? Which Bernoulli equation is being used?

With all this free time, where would the stress come from?

There is a linear relationship between flow rate and head. Low pressure, high head! When there is no liquid material available, the impeller spins idly – where does the pressure come from? As for Bernoulli, check it online
