    The Drinking Straw, Vacuum and Hydrostatics

    I agree that the pressure can support a water column height of approximately 2310 ft if the top end was open: h = 2.31ft/psi * (P2 - P1) = 2.31*(1000 - 14.7) = 2274 ft. However, with the top end closed, doesn't the falling water level "pull" a vacuum at the top? Using a simple hydrostatic...

    The Drinking Straw, Vacuum and Hydrostatics

    I am struggling with a mental model of what happens with the water level in a vertical pipe with the top end closed (say by a valve). Given: Pipe height = 5000 ft Pipe connected at bottom end to a chamber of pressure = 1000 psia water density = 62.4 lb/ft^3 Given a liquid full pipe...
