in this research using the theory of induction motor (um), a um with liquid as secondary part is planned and manufactured. the main objective for planning of this motor is to investigate the possibility of chemical liquids pumping such as liquid poison and acids. results of many laboratory tests are shown to conclude that pumping force in the manufactured pump is dependent on many factors su...

Pumping tests carried out in the fissured layer of a granitic hard-rock aquifer, interpreted at the observation wells by means of the analytical solution of Neuman and at the pumping wells using that one of Gringarten show the vertical anisotropy of this layer of the aquifer; the horizontal permeability being clearly and systematically higher than the vertical permeability. These results perfec...

Purpose. Solving the problem of increasing pumping equipment operational lifetime when pumping-out contaminated groundwater in iron-ore industry by extracting hard, abrasive part, using magnetic filters based on permanent ferrite magnets. Methods. To produce spherical hard-magnetic elements that catch finely-dispersed and weakly-magnetic particles industry, barium powder BaО∙6Fe2O3 is applied, ...

[1] 3-D Hydraulic tomography (3-D HT) is a method for aquifer characterization whereby the 3-D spatial distribution of aquifer flow parameters (primarily hydraulic conductivity, K) is estimated by joint inversion of head change data from multiple partially penetrating pumping tests. While performance of 3-D HT has been studied extensively in numerical experiments, few field studies have demonst...

Characterizing the subsurface is important for many hydrogeologic projects such as site remediation and groundwater resource exploration. Methods based on the analysis of conventional pumping tests have the notable disadvantage that at a certain distance, the signal is small relative to the noise due to the effects of recharge, pumping in neighboring wells, change in the level or adjacent strea...

pressurized irrigation is a recent development that consumes more energy for the pressure produced. in thisstudy, energy consumption, waste and efficiency were investigated at a diesel and electrical sprinklerirrigation pumping plant in some fields in hamadan province during 2007-8. nebraska performance criteria(npc) were used to compare sprinkler irrigation pumping plant performance. the resul...

The paper analyses the effect of electrohydrodynamic (EHD) pumping on the control of natural circulation loops (NCLs). The two major objectives of the investigation are: finding the optimal configuration of an EHD pump and demonstrating that the NCL flow direction can be inverted by exploiting the EHD phenomena. In the initial experimental set-up, we measured the static pressure rise given by a...
