Figure 12.3 The figure shows pressures in vertical tubes due to flow of (a) real fluid through a tube of uniform cross-section, and (b) real fluid through a tube of uneven cross-section.
-Which law or physical principle explains the gradual drop of pressures in vertical tubes in Fig. 12.3(a), and why is the height in the middle vertical tube lower than in the others?
