Why nuclear power station is better than normal power station in generating electricity
In comparison, one kilogram of uranium releases almost the same energy produce by 1 million kilogram of coal (Dittmar, 2009). This energy release because the atom in nucleus split into two fragments and the two fragments split into four and then four to eight and thus a chain reaction starts. At every split, a large amount of thermal energy is released, which is used to heat water to generate power. This is all that happens in all nuclear reactors to produce that huge amount of energy. The

Energy Recovery Devices in Seawater Reverse Osmosis Desalination Plants with Emphasis on Efficiency and Economical Analysis of Isobaric versus Centrifugal Devices
Since the brine reject produced in this process has a high pressure, simply dumping it back into the sea is a waste of energy. This pressure can be reused and thus, the energy could be recycled. This idea led to the innovation of energy recovery devices (ERDs) that prevent the wastage of energy in the SWRO process. The hydraulic energy in the highly pressurized reject brine can be re-used with the help of ERDs, and energy consumption can thus be reduced to significantly high amounts. The

Theoretical Investigations for Convective heat transfer of Nanofluids an Overview
Based on these results, Buongiorno introduced new continuity, momentum, and energy equations for nanofluids. He also modified these momentum and energy equations for turbulent flow in order to develop a correlation for nanofluid heat transfer in turbulent flow, which is:In 1999, Xuan and Li [3] investigated the thermal conductivity of nanofluids using a single-phase theoretical approach. Xuan and Li used a dispersion model to analyze the enhanced heat transfer mechanism in nanofluids rather

What was the Waikato river like before it was dammed ( impact of hydro generation on Waikato river In New Zealand )
It is from the slopes of this mountain region that the water flow to the Waikato River first commences. This initial flow goes by the name of the Waikato stream. From there Taylor traces the flow of water all the way to the North Island. That whole flow makes up a catchment area, which team up with other catchment areas such as those in the Waopa area, and those in sum make up the large catchment area contributing to the considerable water flow at the Waikato. The key characteristic is that the

CHANGE THE TEXT (that is copied from internet),-some information about steel-brick in static analysis
These columns are stocky and possess a large cross-section. Structural failure related to steel columns is buckling. This mode of failure is related to slender columns. Proportionally casted steel columns buckle before steel’s crushing strength. With gradual increment in compressive strength, a value is achieved at the point when the column buckles and deforms perpendicular to its axis and shortens axially in length. This type of load is the buckling load. On reaching the buckling load, steel

Zone 3 is less uniform and replaces illite clays with pyrite to fill its porous structure. It also has quartz and chert crystals as its main components. The rock fragments in zone 3 range from 4-30mm in size. The decrease in porosity of zone three can be observed by the fact that the sonic transit time in this zone is 85 milliseconds. The porosity decrease as we go down to zone 2 and zone 1 but the composition of the sandstone layer remains mainly the same with quartz, chertz and quartz like
