The upstream static pressure (1) is higher than in the constriction (2), and the fluid speed at "1" is lower than at "2", because the cross-sectional area at "1" is greater than at "2". A flow of air through a pitot tube Venturi meter, showing the columns connected in a manometer and partially filled with water. The meter is "read" as a ...
