There are three coefficients of permeability (k) based on three differnt experiments with different sizes of manometer tubes. They are not the same (k = 1.1E-06, 1.4E-06, 2.3E-06). Which value does represent the coefficients of permeability for the soil sample? Should they be averaged?
Sir, i want to ask at the last minute of this video, the equation of k20 = k x kt. Where did you get the value of k ? Based on 3 average of data or what ?
Australian Standard AS 1289 6.7.1-2001. Method of testing soils for engineering purposes: Method 6.7.1 Soil strength and consolidation tests - Determination of permeability of a soil - Constant head method for remoulded specimen. (2) Australian Standard AS 1289 6.7.2-2001. Method of testing soils for engineering purposes: Method 6.7.2 Soil strength and consolidation tests - Determination of permeability of a soil - Falling head method for remoulded specimen.
How can i give you 1000 likes for demostrating it in amazing way
Thank you Sir for your valuable explanation and clear concept conveyance !
#KEEP UP THE GOOD WORK💐 😃🍫
Thanks for sharing this very good explanation sir~
very helpful and nice demostration,
may I know which standard was used to tabulate the data, sir?
Wow sr you did great job😁
Amazing.. luar biasa... 👍👍👍
Is there not a need to have the cell in a water reservoir?
Great person and interesting work
It is helpful me sir
So I thanks for kind information
Hi sir, can we use the same way for concrete samples?

Yes, you will take the average value

Thank you 🤩
can you post a link for the mold/cage in this video?
The mould is commercially available, you can probably find links on the Internet. I don't have one.
sir what is the is the reference of the test procedure that you use ?

How you calculated 'a' ?
From diameter of small tube
Shouldn't the first test be 152 seconds? Because then the value for k1 would be 0.0014 which is much more like the others.
Please share Excel sheet .. observation and report.
I will try to do it in the future when time permits
Very interesting work. If it is a sample with large porosity, can this method be used?
The Constant head is more suitable for coarse-grained soils
Nice video st
Thanks
