Pump and Valve Inservice Testing: How Pump and Valve Testing Evolved [PDF]
ASME/NRC 2017 13th Pump and Valve Symposium, 2017 The O&M Code was developed when it was decided to move Pump and Valve In-Service Testing Requirements from ASME Boiler and Pressure Vessel Code Section XI to a standalone Code. IST for Pumps was originally is ASME Section XI IWP and for Valves IWV. Safety and Relief Valves were a Power Test Code and not in the scope of the ASME Boiler and Pressure ...

Ergodicity of pumping tests [PDF]
Water Resources Research, 2007 Standard interpretations of pumping tests in heterogeneous formations rely on effective representations of porous media, which replace spatially varying hydraulic properties with their constant counterparts averaged over the support volume of a test. Rigorous approaches for deriving representative (effective, apparent, upscaled, etc.) parameters employ

, 2000 Two constant discharge, multiple well pumping tests were performed in the Congaree aquifer at the H-Area seepage basins during the weeks of April 30 through May 11. The purpose of the tests was to collect information that might determine the source of groundwater contamination in the Congaree aquifer and to estimate the hydraulic parameters of the ...
