Typical piping connection to single cell cooling tower

Here typical piping connection to single cell cooling tower For the tower piping circuit, the pump must overcome the piping flow friction loss; piping, condenser, cooling tower losses, and valves. It must also provide the energy head necessary to raise water from a low to a higher static head level. Most discussions concerning tower and/or open piping circuits would simply define the required pump static energy head as Ho (in Figure 3); the “open” height of the piping circuit. This is, however, an ever-simplified assumption which may or may not be true depending on whether or not a “siphon draw” is established in the down comer return piping DE. The nature of the down comer siphon draw and its limitations should be evaluated. including air discharge , sanitary sewer drain , sump drain , sump plug  air intake , continuous  overflow pipe  to drain , to condenser water pump , 25mm  pipe union to permit removal for inspection and test , air intake for more details download this file
