assumed to be 0.01 feet for steel interconnects and 0.0001 for the existing HDPE <br /> interconnects. <br /> 4.3.1.2 Minor Losses <br /> In addition to the friction energy losses, minor energy losses (Ke) were also included in the <br /> analysis. Minor losses are typically smaller in magnitude than the pipe friction losses. The <br /> loss coefficient method was employed to determine the minor energy losses for the system. <br /> The loss coefficients are multiplied by the kinetic energy to calculate the system minor <br /> losses. The loss coefficients used in the analysis are shown in Table 5. <br /> Table 5: Minor Loss Coefficients <br /> Minor Loss Coefficient <br /> Entrance 0.50 <br /> Trash Rack 0.50 <br /> 45 degree fitting 0.40 <br /> 75 degree fitting 0.90 <br /> Exit 1.0 <br /> G EI .. .,,. <br /> Hydrology and Hydraulics 14 <br />
