Calculate the total head and select the pumpCalculate the NPSH available and check with respect to the NPSH requiredCalculate the specific speed and predict the pump efficiency. The plot starts at zero flow. The mass flowrate of the system is established on the process flow diagram by the mass balance. And what is the optimal operating point of a centrifugal pump?How to do details calculations that will allow you to size and select a centrifugal pump?How to verify that your centrifugal pump is p
