Slug test calculations

This is important in slug tests because many models assume that the flow rate can be accurately calculated from the measured pressure changes. A slug test involves the instantaneous injection or withdrawal of a volume or slug of water or solid cylinder of known volume. This is accomplished by displacing a known volume of water from a well and measuring the artificial fluctuation of the groundwater level. The primary advantages of using slug tests to estimate hydraulic conductivities are numerous. Issues In Conducting and Analyzing Underdamped Slug Tests • Test lasts only a few seconds – Need p-transducer that responses rapidly (< 1 sec) • Hard to make ho instantaneous – Can use time of peak or trough for start time • P-transducer should be located near water surface This webinar discusses using slug tests to evaluate an aquifer.

STEP1 - Graph slugtest data - Log Head Vs. Linear Time. Read h1,h2,t1,t2 from straight line part of curve. STEP2 - Look up well construction paramters. STEP3 - Enter test parameters. Describes how to use the slug test data sheet with some suggestions about conducting slug tests A number of methods have been developed to calculate hydraulic conductivity (or permeability) from slug test data. We usually use the Method of Bouwer and Rice (1976)to obtain hydraulic conductivity from raw slug test data. This method was originally 2019-08-18 The slug test data provided estimates of the hydraulic conductivity of the aquifer immediately adjacent to the boreholes.

It is calculated as total bases divided by at bats. Slugging Percentage Do a quick conversion: 1 pounds = 0.031080950037834 slugs using the online calculator for metric conversions. Check the chart for more details. Example Calculation.

2011-09-28 · Description The slug tester is used to accurately determine the optimum dosing disk height for any size capsule (000, 00, 0, 1, 2, 3, 4, 5) relative to the product Comparison of results from the instream slug tests and empirical calculations showed that Hazen and Harleman equations produced results of K similar to those from the slug tests whereas the Krumbien and Monk and the Kozeny-Carmen equation overestimated the K values of the streambed material.

The slug test method is designed for mini-piezometers or wells, and is used to estimate hydraulic conductivity (Kh).

By Keith J. Halford and Eve L. Kuniansky. Preface. This report documents several spreadsheets that have been developed for the analysis of aquifer-pumping test and slug-test data.

See how to open the piping model file. Input data: Diameter of discharge pipe: 21.9 sm; Wall thickness of discharge pipe: 1.6 sm; Product: steam + water; Velocity 40 m/s; Water density ρ=0.001 kgf/sm³; Calculation: The slug test data provided estimates of the hydraulic conductivity of the aquifer immediately adjacent to the boreholes. Pump tests were conducted using downgradient wells in high-hydraulic conductivity zones (based on slug tests) to determine their areas of influence. The tests were analyzed to determine hydraulic conductivity.
