CEEN 341 - Lecture 2 - Particle Size Analysis
This lecture covers how geotechnical engineers develop particle size distribution curves and why they are important. The sieve analysis and the hydrometer analysis are discussed, and example calculations are presented.
Learning Objectives:
1) Explain why particle distribution is important to engineers
2) Explain the difference between a mechanical (i.e., sieve) analysis and a hydrometer analysis
3) Develop a particle size distribution curve from sieve and/or hydrometer data
4) Calculate the uniformity coefficient and the coefficient of gradation
5) Correctly classify whether a coarse-grained soil is well-graded or poorly graded

you are honestly fun and effective. two of my favorite traits. i am ever grateful for your videos and for now offer my sincerest gratitude for the excellence of your existence.
Thank you Professor, the lecture was fully informative, clear and had a better understanding of the concepts. looking forward for somemore lectures from you. Great job.
Amazing presentation, thank you very much for sharing!
Great class as always.
Great video on Sieve analysis
wish he were my teacher.
Hello, thanks for the great videos . I would love it if I know the name of the text book you are using . Thank you again
Which of the three main clay minerals undergo large volume change in contact with water and why?
Dr, after greetings, I would like to know how can I calculate the CM values of CM diagram from the distribution curve where C is the coarsest one percentile and D is the median. Is C value refers to 1% or 99%?
Please What is the formula to calculate size or no of next sieve by the percentage of passing or retained on previous sieve
Thank you so much!
where can I download the students lecture notes?
Happy Holiday Dr.Franke. I followed the lecture and tried to plot log scale in excel. I am wondering what factor or reason should I consider when we decide x axis decreasing (1000 to 100 to 10 to..0.01) or increasing as normal. My graph would it be same if x axis goes increasing from 0 to 1000. Thank you!
Dear sir pls upload video for shallow and pile foundation
And where i can find these ppt? please.
Sir from where someone can get lecture slides?
Ironically, had a FE Exam question about a 'gap graded' soil.
17:05 why would they call it the exact opposite way of the other's? geologists and engineers..
How do we find the Mean particle size? what is the formula used? is there an examlpe with numbers? Thanks
Why are there so many ads? Barely 5 mins into the class and you get hit by ads
8:24 which book?

We were informed that Engineers use "Well Graded", whereas Geologists use "Poorly sorted". Also "Poorly Graded" would be "Well sorted". Which makes sense, because something that is highly graded will have a large variety of shapes and sizes, which also means that the sample is poorly sorted by size and shape.
Actually engineers somtimes confused between gradded and sorted...
You sound like tom selleck
**Tthsk + dramatic inhale** Did you notice that you your mouth does a clack for each new slide?? It’s annoying and also it’s not necessary to indicate that you’re moving on because by the time you do it the slide has already changed 😅 do you have this verbal tick when teaching too? Does the *tsk* sharp inhale thing have meaning that in misssing? Do you *tsk* sharp inhale intentionally or is it like a reflex? It’s annoying as frickin heck but also I can’t imagine why you’re doing it either….. can you get a pen to click over and over instead? I think that’s slightly less annoying during a LECTURE….
