Pump Pressure Gauge
Why does the efficiency of centrifugal pump increases as pressure gauge value increases?
It doesn't necessarily. Look up some pump curves: google pump manufacturer to find some. Efficiency curves are basically concave down parabolas (arc's). The peak is in the middle at the design pressure, and the efficiency drops at either high or low pressure.
For basically any pump, at no pressure, high flow, efficiency is low because power is consumed but little energy out, as energy out = Pressure * Flow. At high pressure, no flow, also about zero efficiency. Somewhere in the middle is the design point, with the max efficiency.
