The following article will guide you about how to generate biogas from waterweeds. Introduction: Waterweeds provide widely available feedstock for biogas generation. Water-hyacinth and algae are two major categories of waterweeds. A number of experimental studies have been carried out in past both in India and abroad to estimate potential, and develop the related technology. […]

While porosity is a measure of the water-bearing capacity of the formation, all this water cannot be drained by gravity or by pumping from wells, as a portion of the water is held in the void spaces by molecular and surface tension forces. The volume of water, expressed as a percentage of the total volume […]

Ground water moves from levels of higher energy to levels of lower energy, its energy being essentially the result of elevation and pressure, the velocity heads being neglected since the flow is essentially laminar. The velocity is very small in the laminar range—of the order of 1 cm/sec—and the Reynolds number (Re) for ground water […]
