Problem 1: [6] Static Pressure Head Pascal's barrel is the name of a hydrostatics experiment allegedly performed by Blaise Pascal in 1646. The aim of the experiment is to demonstrate hydrostatic pressure by exploding a barrel of water by connecting a thin and tall pipe to it and filling it with water. This experiment was successfully demonstrated at Princeton University in 2016. Watch the video Pascal's Blaising Barrel-Exploding Glass Barrel with Water Pressure in which 1L of water is used to explode a 50L glass barrel which is rated to withstand a pressure of 25 psig. a. [2] Now imagine that the height of the "straw" used in the experiment was 50. ft. Calculate the new pressure exerted by this column of water on the barrel in psig and in psi. b. [2] Is the pressure large enough to explode the barrel at this height? c. [2] What is the minimum height needed for the barrel to break? Pascal's law and hydrostatic paradox is further explained in the follow-up video The Hydrostatic Paradox-Explained. These videos are also found on Canvas in the hydrostatic pressure module. These videos are excellent and worth your time to watch.
