Smiths Canal Pump Plant <br /> Monitoring Well <br /> Grout Volume Calculations <br /> i <br /> Monitoring Wells MWI, MW2, MW3, MW4, and MW7: <br /> Assumptions: Borehole diameter is 8 inches diameter <br /> Volume of annulus between casing and hole = 2.44 gal/linear ft <br /> Volume of 2-inch diameter casing = 0.17 gal/linear It <br /> Filter pack porosity is 25% <br /> Grout Volume for well MWl = 29 ft 0.17 al/linear ft. + 0.25 23 ft 2.44 al/linear ft <br /> ( )( 8 ) [( )( 8 )] = 18.96 gallons <br /> Grout Volume for well MW2 = (26 ft)(0.17 gal/linear ft.)+ 0.25[(21 ft)(2.44 gal/linear ft)] = 15.41 gallons <br /> Grout Volume for well MW3 = (30 ft)(0.17 gal/linear ft.)+ 0.25[(24 ft)(2.44 gal/linear ft)] = 19.74 gallons <br /> Grout Volume for well MW4 = (36 ft)(0.17 gal/linear ft.)+ 0.25[(25 ft)(2.44 gal/linear ft)] = 21.37 gallons <br /> 1 <br /> Grout Volume for well MW7 = (25 ft)(0.17 gal/linear ft.)+ 0.25[(22.5 ft)(2.44 gal/linear ft)] = 16.22 gallons <br /> Monitoring Wells MW5 and MW6: <br /> Assumptions: Borehole diameter is 8 inches diameter <br /> Volume of annulus between casing and hole = 3.42 gal/linear ft <br /> Volume of 4-inch diameter casing = 0.66 gal/linear ft <br /> Filter pack porosity is 25% <br /> Grout Volume for well MW5 = (29.5 ft)(0.66 gal/linear ft.)+ 0.25[(22.5 ft)(3.42 gal/linear ft)] = 38.71 gallons <br /> Grout Volume for well MW6 = (29.5 ft)(0.66 gal/linear ft.)+ 0.25[(22.5 ft)(3.42 gal/linear ft)] = 38.71 gallons <br /> Total Grout Volume = 169.12alg Ions , <br /> I <br /> W:\13099\wp-wellabandonment.doc <br /> I <br />
