Study of the effect of particles size and volume fraction concentration on the thermal conductivity and thermal diffusivity of Al2O3 nanofluids

In this study we present new data for the thermal conductivity enhancement in four nanofluids containing 11, 25, 50, and 63 nm diameter Aluminum oxide (Al2O3) nanoparticles in distilled water. The nanofluids were prepared using single step method (that is, by dispersing nanoparticle directly in base fluid) which was gathered in ultrasonic device for approximately 7 h. The transient hot-wire laser beam displacement...

Modelling of solar radiation for West Africa: The Nigerian option

The United Nations Framework Convention on Climate Change (UNFCCC) reports indicate that those who are least responsible for climate change are also the most vulnerable to its projected impacts. In no place is this more evident than in Sub Saharan Africa, where greenhouse gas (GHG) emissions are negligible from a global scale. In Africa, energy demands could be the major factor that may lead to the increase of its...

Novel method of iron removal from underground dug well waters in communities around Okada town, Ovia North-East L.G.A. Edo State

Some indices of pollution were studied in water samples from 25 dug wells randomly selected from Okada town and it’s environ. Physicochemical parameters measured include temperature, pH, colour, turbidity, total dissolved solids (TDS), toxic shock syndrome (TSS), total hardness, Ca, Mg, Fe, Mn, nitrate and phosphate etc. The results of the study showed that dug wells from this area contain Fe and Mn concentrations...

Assessment of leachate effects to the drinking water supply units in the down slope regions of municipal solid waste (MSW) dumping sites in Lahore Pakistan

The aim of this study was to evaluate seasonal as well as moderate temporal effects on deep groundwater quality by the dumpsites leachate in the Lahore Metropolitan with a population of about 8 million. Groundwater samples for this study ware drawn from groundwater supply units installed by local government for the provision of drinking water to the residents. The groundwater in down slope regions from municipal solid...
