ABSTRACT Sand gravity filters can be automated to suit your requirements. Be it industrial or domestic this model can be implemented with ease. This research is mainly focused on getting sand gravity filters in industries automated using measurable variables like flow and level. The controls are based mainly on monitoring the filter tank level versus the outlet and inlet flows. Inlet flow and outlet flow are regulated to maintain a certain level beyond which the filter tank will be deemed flo...

Abstract The laminar boundary layer flow in an exponentially stretching stenosed artery immersed in viscous and incompressible blood is investigated along with the effect of a chemical reaction. Many researchers have used mathematical modelling to predict blood flow through stenosed arteries. Pressure, shear stress and velocity are the parameters that have been analysed in the past. Not a lot of work has been done to highlight the effect of heat transfer on an exponentially stretching stenose...
ABSTRACT The interaction of landuse/Landcover (LULC) and climate change, to a large extent, involves anthropogenic activities. This interaction has brought about a complex global environmental change which includes biodiversity loss, land degradation, deforestation, afforestation and forest degradation among others. Such change is manifested through the dual nature of landuse/landcover both as causal factor and as effect of climate change. LULC is initiated through human activities such as fo...
ABSTRACT Accessions Tvu 3788 and IT 99K-377-1, Tvsu 102 and Tvsu 1685 and ACR.91SUWANI-SRC1 and DMR-LSRW of Cowpea (Vigna unguiculata), Bambara groundnut (Vigna subterranean) and Maize (Zea mays) respectively were subjected to lead (Pb) and zinc (Zn) treatment and screened for their ability to tolerate these metals. Accessions Tvu 3788, Tvsu 102 and ACR.91SUWANI-SRC1 of cowpea, bambara groundnut and maize respectively were chosen and used for the experiment. The toxic effects of lead and zinc...
BSTRACT In this thesis the Gaussian plume model is proposed as a method for solving problems related to the transportation of pollutants due to advection by wind and turbulent dif- fusion. The idea of advection and diusion is fundamental to this thesis as well as its mathematical derivations from the initial principles to the explanation of the governing partial dierential equation. Dimensional analysis technique has been employed as well as Fick's rst and second law of diusion. The concentra...
