This is a much better procedure than what I did for an undergraduate Ecology research project. I really like the usage of the plunger (we rotated the 1000 mL cylinders end over end, sketchy!) and the replication of the 30 s measurement. I imagine the data collected from this experiment is much more accurate than our single trials with each soil sample.
Some soluble salts release flocculating cations, e.g. Ca++, Mg++, Na+, and K+, favoring the flocculation of clay minerals in a soil sample. If you analyze a sample for particle size when clay minerals are flocculated, i.e. clumped together, you will obtain erroneous readings. Tap water may favor the flocculation of clay minerals because it contains flocculating cations such as Ca++. It is more appropriate to always use deionized water instead.
The course is called geotechnical engineering. The profession would be the same. It has uses in the mining industry, foundation design, landscape design (landfills and what-not) as well as many others.

Nice job showing how the whole procedure works in a video format! I really thought it was well presented, both visually and with your explanations.

Thanks for the valuable clarification! one thing was ambiguous to me is how you prepared the four soil samples after calibration step!

thank you very much for sharing this video. it help me a lot. i'm gonna do this.
This is amazing video, thank you so much. Very informative video. Great explaining bro. :)
Can you please tell me about hydrometer specifications like its length in mm, scale temp range
Good luck with your analysis.
Hi .. where's can I find the 24 hr readings and the calculation part for this method?
In my granulometric analysis all my targets were always above zero (negative indication). Could I 've done something wrong?
thank you for share this Good Knowledge.
Very good presentation.
thank you. its very useful.
am happy to be 1k th subscriber
Do happen to know where I can purchase a plunger? These little guys are very hard to find.
very good use ful for students
that good for studying and easy.
nice vidoe
thank you
Thank you so much, its very usefully
course and profession related to that analysis?
thank u
Thann you
Good
shout out to wafa's geotech 1 class let's goooo
That looks like a gross milkshake!!!!
theek ha par itna be achaa nahi hein
Thann you
