Before diving into the calculation process, it's vital to grasp what pump head signifies in the context of chilled water systems. The pump head, often measured in feet of water (ft), meters of water (m), or pounds per square inch (PSI), represents the total pressure that a pump must develop to move water through the system against resistance. This resistance includes friction losses in pipes, fittings, valves, and the pressure required to overcome the elevation difference between the pump and the highest point of water distribution. chilled water pump head calculation excel sheet
