[@vedantsuryawanshi2920]

Thank you Sir for your valuable explanation and clear concept conveyance ! #KEEP UP THE GOOD WORK💐 😃🍫

How can i give you 1000 likes for demostrating it in amazing way

[@emmalee2520]

very helpful and nice demostration,

[@PetualangWawasan]

Thanks for sharing this very good explanation sir~

[@muhammadfirmanpratama543]

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 ?

[@royal_backchod_5848]

Wow sr you did great job😁

[@omedmuhammad2674]

Great person and interesting work

[@febrilukitoz1154]

Amazing.. luar biasa... 👍👍👍

[@varietychannel5825]

Hi sir, can we use the same way for concrete samples?

[@r.sanjay2623]

It is helpful me sir So I thanks for kind information

[@erenjagaer5280]

may I know which standard was used to tabulate the data, sir?

[@judeclancy1952]

Is there not a need to have the cell in a water reservoir?

[@hydromanor]

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?

[@GeoEngineeringandScience]

Yes, you will take the average value

[@tejara01]

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.

Thank you 🤩

Very interesting work. If it is a sample with large porosity, can this method be used?

[@mongimene1314]

The Constant head is more suitable for coarse-grained soils

[@juliadelacruz5858]

can you post a link for the mold/cage in this video?

[@GeoEngineeringandScience]

The mould is commercially available, you can probably find links on the Internet. I don't have one.

[@royal_backchod_5848]

Nice video st

[@meinardomagtibay7958]

sir what is the is the reference of the test procedure that you use ?

[@GeoEngineeringandScience]

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.

Thanks

[@vivekmishra2105]

Please share Excel sheet .. observation and report.

[@GeoEngineeringandScience]

I will try to do it in the future when time permits

[@grizzlyedu]

How you calculated 'a' ?

[@thundergaming7206]

From diameter of small tube
