Grinder Pump Report <br /> Pumping characteristic requirements are provided for North Sound Behavioral Health Treatment, which <br /> represents the most restrictive characteristics of the proposed building to be pumped. Refer to the site <br /> map in Appendix A-1 and detailed calculations in Appendix A-2. <br /> 1.0 Static Lift <br /> Finish floor elevation of building = 94.30 <br /> High point of pressure main = 100.88 <br /> Pump off elevation = 84.51 <br /> Tank bottom = 82.84 <br /> Static lift 100.88—84.51= 16.37 <br /> 2.0 Friction Losses <br /> 2" <br /> 0 @ 17.2 0 <br /> 0 @ 1.4 0 <br /> 0 @ 5.2 0 <br /> 0 @ 2.8 0 <br /> 259 If 2-inch pipe 259 <br /> 259/100 2.59 <br /> (Friction factors for pipefittings in terms of equivalent 100 feet of straight pipe.) <br /> 3.0 Operating Point <br /> 3.74 gpm: 16.37 + 0 + (2.59)(0.05)= 16.50 <br /> 15.20 gpm: 16.37 + 0 + (2.59)(0.72) = 18.23 <br /> WEIL-WILO Model WEIL 2516 grinder pump will discharge approximately 67 gpm at 52.00' <br /> TDH. The WEIL 2516 pump can discharge to a pressure of 31.32 psi within typical operating <br /> pressures (approx. 72.24'), which will overcome any potential variations regarding pump <br /> operation elevations. <br /> 4.0 Design <br /> Use 5,392 gallons per day(Average Daily Flow): <br /> 3.74 gpm — average <br /> Use a peak factor of 4.06: <br /> 15.20 gpm — peak <br /> Use a suggested design of 67 gpm to handle high flow rate: <br /> WEIL 2516 grinder pump is adequate <br /> Grinder Pump DIEICIS <br /> North Sound Behavioral <br /> ral Health Treatment 1 <br /> AHBL No.2170857.10 <br />
