Understanding Centrifugal Pump & Motor Torque-Speed Curve

Like pumps, motors produce a torque-speed curve of their own. By overlaying the torque-speed curve of a pump and a motor, one can verify that the motor is producing enough accelerating torque to drive the pump to full speed, as shown below. In this overlay the shaded area reflects the accelerating torque available from the motor to drive the pump.
