Siam's answer on the our latest physics project on pressure. We sometimes say that a picture is worth a thousand words, and Siam's answer is a good demonstration of that. We liked the figure he gave us and that pretty much answered the project question without much words. Thanks for all your effort in putting the figure, picture and even the added bonus on Torricelli and his introduction. One of the best answer!. Here is the full answer and a screenshot: https://docs.google.com/document/d/1UhZ3rkW8i8uX5mfRrteX6TFhtxt76VbaujwRzmohF3Q/edit?usp=drivesdk
