Pump Curve Speed Calculator

This centrifugal pump curve calculator is meant to quickly calculate the different operating conditions when a centrifugal pump is sped up or slowed down. Using affinity laws, we can accurately calculate the pressure, flow and required speed and power of a pump from a specific known set point. Enter information as instructed below and press calculate.
