Deflection range of water in heterogeneous permeable media

Abstract

Knowledge of mode of transport of fluid in soil is the basis for soil environmental engineering especially in transport of contaminants in groundwater. The study investigates the possible minimum and maximum angle of deflection of water through media of different porosities for the purpose of environmental pollution control. An established equation which relates angle of deflection with porosity ratio was used to determined angle of deflection. The minimum and maximum deflection angles were found to be 17.80 and 53.50 respectively for sands with porosity ranging from 0.25-0.42, while for sands categorized under fine and medium, the maximum angle of deflection was found to be 69.10.

Keywords: porosity ratio, deflection angle, volume flux, inlet pipe, outlet pipe.
