A From Nyquist plot to real conductivity spectra (sigma)

AI Thread Summary
To convert a Nyquist plot into a real conductivity vs. frequency plot, one must derive the real part of the complex conductivity from the impedance data. The discussion highlights the need for clarity on whether the imaginary part is necessary for this transformation. Users share their methods for calculating real conductivity, emphasizing the importance of correct formulas for admittance. The original poster seeks guidance on ensuring their calculations are accurate. The conversation centers on the mathematical relationships between impedance, admittance, and conductivity.

From Nyquist plot to real conductivity spectra (sigma) vs frequency
Hi, I have data of impedance but due to limitation of software after measurement I do not receive numerical values for admittance and real conductivity vs frequency. How mathematically I can convert Nyquist plot into plot real conductivity vs frequency?

Your plot already shows the real part of the complex conductivity. Do you need the imaginary part?

The image is the result I want to get. For now I have Nyquist plot Im vs Re, which I would like to transform it to the plot you see attached, real part of complex conductivity vs frequency. I have done it trough admittance but I am not sure in all formulas I used for it...
 
Please, show us your method.
 

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
