Capture zone calculation

Typically, application of science involves prediction of function such as determining at what rate a well must be pumped to create a suitable capture zone. What period of time will be required to biodegrade a mass of contaminant within a plume How much activated carbon will be required to treat the discharged vapor What will be the cost of electricity to power the remediation system Engineers are more likely capable of designing a balanced remediation system that has flow rates matched to reaction times or water-air contact rates. Tank sizes, power consumption, and similar rate-time-related calculations also fall within the specialty of the engineer. 

Important to any aquifer restoration program is the radius of influence or capture zone to be anticipated during pumping. The radius of influence (rQ) for a vertical pumping well can be calculated using the following equation.

In the thermal breeder reactor, is produced from Th. The reactor may be designed either with a core containing a mixture of Th and or with a central zone core) of surrounded by an outer layer blanket) of Th. However, it is necessary to minimize parasitic neutron capture in structmal materials including monitoring systems, control rods, etc. Calculations have shown that a conversion ratio of 1.06 should be possible. 

After the second boat is removed, the first boat is placed into the heated zone of the combustion tube. The cap is screwed into place, heating mode "3" is selected, and start is pressed. The mercury response finm this run is captured by the data acquisition software and used to calculate a reagent blank. The second boat is treated in a similar manner. It is important to allow sample boats to cool to ambient temperature before proceeding with sample measurements. 

Calculation showed that capture area of stagnation zone differs at various time. So the reversing a well at three different time are considered to get an optimal value of extraction degree a) T = 100 days, b) T = 200 days, c) T = 300 days.
