(SGEOFLOW Job Description: 10498 S.Airport Rd,Manteca Contact: I James Bamard Prepared b RBM Date: 3/21/2021 Please fill in the shaded areas and drop down menus: This spreadsheet serves as a guide,and is not a complete hydraulic design. Pressure losses may be grossly overstated,particularly if designing with WASTEFLOW Classic The letters on the diagram(right)match the letters in section 2 below. Worksheet- Pump Sizing Section 1 -Summary from Worksheet 1 Flow required to dose field 4.42 gpm Flow required to flush field 3.70 gpm Flow required to dose&flush field 8.12 gpm Filter BioDisc-150 No.of Zones 1 zones Zone valve Dripline Wasteflow PC-1/2gph Dripline longest lateral 100 ft. Section 2 Ft of head Pressure A. Flush line-Losses from end of dripfield to tank Return header pipe size 1.25 inch Pressure loss in 100 ft of pipe 3.65 ft. 1.58 psi Distance from furthest dripline end back to tank ft. Equivalent length of fittings ft. Elevation increase or decrease ft. Total pressure loss from end of dripline to return tank 4.0 ft. 1.74 psi B. Dripline-Losses through Wasteflow dripline Fill in the length of longest dripline lateral 100 ft. Minimum pressure required at end of dripline 23.10 ft. 10.00 psi Loss through dripline during flushing 0.35 ft. 0.15 psi Total minimum required dripline pressure 23.45 ft. 10.15 psi A+B. Minimum Pressure required at beginning of dripfield CALCULATED pressure required at beginning of dripfield 27.47 ft. 11.89 psi SPECIFIED pressure at beginning of dripfield(from worksht 1) 69.3 ft. 30.00 psi Greatl SPECIFIED Pressure is greater than CALCULATED Pressure requirement.Go to next step C.
