Figures (a) and (b) refer to the steady flow of a (non -viscous) liquid . Which of the two figures is incorrect ? Why ?

Explanation

Figure (a) is incorrect . It is because of the fact that at the kink , the velocity of flow of liquid is large and hence using the Bernoulli.s equation the pressure is less . As a result , the water should not rise higher in the tube where there is a king. This is shown in figure (b) . For this liquid may be incompressible .
