Pump Selection I

• composite curves that show the operating range of various pumps.
• The goal of line sizing is to provide the appropriate pipe sizes for the suction and discharge lines of the pumping system. These sizes are selected based on a set of criteria.
• The goal of carrying out pump hydraulic calculations is to determine the total head of the pump.
• The intersection of the system curve and the pump performance curve is the pump operating point, which determines the characteristics of the pump that we need.
• The system curve relates the system pump head requirement (Ws ) to the specific flow (Q) and the system loss parameters (friction).
• The performance curve of a pump will help us specify its final set of characteristics.
