Sellers debates the benefits of using graphical solutions to answer algebraic questions. Sellers outlines how the interaction of a centrifugal load like a pump or fan needs to be considered in the context of the rated motor speed for the motor serving it. In Sellers’ first table, he illustrates what happens if a pump that is rated for a given operating condition at 1,750 rpm is connected to three different motors, each of which as a different rated speed at full load. In the next graph, Sellers illustrates how when plotting speed vs. load data for a motor on an axis, there needs to be speed vs. bhp for the pump on the same axis.
