Efficiency derating values are displayed on the curve in order to help account for:
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.
Of the following, which does the actual work of moving the water?
Bowl lateral clearance is sometimes displayed on the pump curve to help account for:
