GWPD 10—Estimating discharge from a pumped well byuse of a circular orifice weirVERSION: 2010.1PURPOSE: To estimate the discharge from a pumped well from a non-vertical standard pipe by using acircular orifice weir.Materials and Instruments1.Steel orifice plate2.Hand level3.Piezometer tube, 1/8-inch or 1/4-inch diameter4.Glass tube, 1/8-inch or 1/4-inch diameter5. Accurate yardstick, or other suitable ridged scale6.Graduated tape7.Pencil or pen, blue or black ink. Strikethrough, date, andinitial errors; no erasures8.Field notebook9.Groundwater Site Inventory (GWSI) System Groundwater Site Schedule, Form 9-1904-AData Accuracy and Limitations1. The circular orifice weir method is accurate to within2 percent.2. The hole in the steel plate of the orifice weir must beaccurately cut, be centered, be circular, and have a beveled edge. The steel plate restricts the flow through theorifice and creates a pressure head in the discharge pipe.3.For the orifice weir to function properly, the gate valvethat controls the rate of discharge must be placed at least10 pipe diameters from the piezometer tube connectionto keep pipe turbulence to a minimum.4. The piezometer tube must be completely free of anyobstruction and free of air bubbles when a reading ofthe pressure head is made. The head in the line is cor-related with discharge by use of tables calibrated for theparticular ratio between the orifice and the discharge pipediameters (table 1).5. The discharge pipe must be level, and the water flowfrom the end of the discharge pipe must fall freely.Advantages1. This method provides an accurate means of determiningthe discharge rate from turbine or centrifugal pumps.2.No special training is needed to use this method.Disadvantages1. This method cannot be used to measure the pulsatingflow from a piston pump.2. Well flow must be constant.Assumptions1. An appropriately sized orifice plate is available and wasbuilt accurately.2. The diameter of the orifice plate is less than eight-tenthsof the inside diameter of the pipe that serves as the channel of approach.3. The last 6 feet of the discharge line is level and containsa fitting that is screwed into a 1/8-inch or 1/4-inch tappedhole centered on the discharge line, exactly 24 inchesfrom the orifice plate.
82 Groundwater Technical Procedures of the U.S. Geological SurveyInstructions1.2.3.Figure 1 shows the essential details for setting up acircular orifice weir for measuring the discharge rate ofa well that is being pumped with a turbine or centrifugalpump.Select an appropriately sized circular orifice weir andattach it to the end of the discharge pipe. Table 1 lists3- to 10-inch circular orifice weirs that can be used withdischarge pipes ranging from 4- to 12-inches in diameter.Place a short piece of glass tubing into the upper end ofthe piezometer tube. Attach the lower end of the piezometer tube to the fitting on the discharge line that is located24 inches from the orifice plate (fig. 1). Tape the piezometer tube to the scale making sure that the zero mark onthe scale lines up with the center of the piezometer fittingin the discharge pipe.4. The water level in the piezometer tube represents thepressure in the approach pipe when water is beingpumped through the orifice. The water level can beobserved in the glass tube.Between water-level readings, check for air bubbles inthe piezometer tube. If air bubbles are present, they canbe eliminated from the piezometer tube by dropping thetube between readings so that water flows from it.8.Record estimated discharge in the field notebook and inthe discharge data section of the GWSI Groundwater SiteSchedule (fig. 2, Form 9-1904-A).Data RecordingData are recorded in a field notebook. Discharge datashould also be recorded in the discharge data section of theGWSI Groundwater Site Schedule (Form 9-1904-A).ReferencesDriscoll, F.G., 1986, Groundwater and wells (2d ed.): St. Paul,Minnesota, Johnson Filtration Systems, Inc., 1089 p.Hoopes, B.C., ed., 2004, User’s manual for the National WaterInformation System of the U.S. Geological Survey, GroundWater Site-Inventory System (version 4.4): U.S. GeologicalSurvey Open-File Report 2005–1251, 274 p.5. To read the pressure head in the glass tube, hold thepiezometer tube in an upright position perpendicularto the discharge pipe. Read the water level using theattached scale.6.7.Determine the well discharge from table 1. For example,if the pressure head is 25.5 inches, the orifice plate is5 inches in diameter and the discharge pipe is 8 inchesin diameter; follow the 25.5-inch line from the left scaleuntil it intersects with the 5-inch orifice and 8-inch pipecolumn. The well discharge rate obtained from table 1 is500 gallons per minute.Layne & Bowler, Inc., 1958, Measurement of water flowthrough pipe orifice with free discharge: Memphis, TN,Layne & Bowler, Inc., Bulletin 501, p. 22–25.U.S. Geological Survey, Office of Water Data Coordination,1977, National handbook of recommended methods forwater-data acquisition: Office of Water Data Coordination,Geological Survey, U.S. Department of the Interior, chap. 2,p. 2-17.1/16 inch605959575655541/8 – 3/8 inchDetail oforifice platePiezometer tubeGate valve13121110987654321ScaleOrifice plate4 feet, minimum24 inchesFigure 1.
