Efficiency derating values are displayed on the curve in order to help account for:
Of the following, which does the actual work of moving the water?
One advantage of the electronic curve over the hard-copy curve is that the electronic version has already accounted for the effect of a limited number of stages when displaying head, efficiency, and Brake Horsepower.
Bowl lateral clearance is sometimes displayed on the pump curve to help account for:
