Question 1139779
.
<pre>
1.  Use the Thiem Equation to estimate the transmissivity T


    T = K*b = {{{(Q/(2*pi*(s[1]-s[2])))*ln(r[2]/r[1])),


where Q = 100 m^3/min,  {{{r[1]}}} = 10 m;  {{{r[2]}}} = 50 m;  {{{s[1]}}} = 3 m;  {{{s[2]}}} = 0.05 m.


    T = 0.87 m^2/min;  then for conductivity  K = {{{T/b}}} = {{{0.87/8}}} = 0.11 m/min.



2.  Actually, such problems are for mature hydrology students or professional hydrogeologists - 
    - not for placing / posting to this forum.



3.  Do not be amazing my professional knowledge in hydro-geology.

    I worked for many years for hydro-geology engineers in different countries, developing computer software 
    and making numerical (computer) simulations for them on groundwater flow and mass transport.


    My highest personal key development was a computer code to simulate lenses of light petrol (hydrocarbon) product 
    flowing at the surface of a groundwater flow.


    In the second half of nineties and the first half of 2000-2010 years, these issues were at the forefront 
    of the hydro-geology science.
