That is the genius and great presentor professor William Kitch. I wonder why he did not identify himself in this video.I always enjoyed his videos and benefited from his knowledge.
Dear sir Thanks for your lectures. One of the projects where the permeability is needed for the top 5 meters. The well is a semi penetrating unconfined aquifer, but we reach a depth of 30 m and no aquiclude has been encountered. What is the thickness of the aquifier (H) that should be used in the equation in this case? In addition, I don't understand how the thickness of the unconfined aquifier can affect the flow rate into the semi penetrating well. Assuming the well is 5 meters deep, does it make any difference in the flow into the well if the aquiclude is 10 meters or 100 meters deep
You fill the Mariotte bottle from by opening the vent line at the top of the bottle and using the fill line just above the specimen. Water does flow out of the specimen and bucket, but not as fast as you fill it. The water does rise up the standpipe during filling, but doesn't go above the top of the bottle.
this helped me pass my lab test in soil mechanics

Thank you very much sir, please continue in this great videos much respect . 🤗
How does water not come out from the bucket or standpipe when filling up the Mariotte's bottle?

really good explanation!
At 6:10 he's using diameter squared x pi. Shouldn't he be using radius squared x pi ?
radius is half a diameter, so when u plug that in to radius square * pi it will be this:
(D/2)^2 * pi
which simplifies to: (D^2)/4 * pi
