Question
Figures(a) and (b) refer to the steady flow of a (non viscous) liquid. Which of the two figures is incorrect? Why?
✓
Answer
Fig. (a) is incorrect. According to equation of continuity, i.e., av = Constant, where area of cross-section of tube is less, the velocity of liquid flow is more. So the velocity of liquid flow at a constriction of tube is more than the other portion of tube. According to Bernoulli’s Theorem, $\text{P}+\frac{1}{2}\rho\text{v}^2$= Constant, where v is more, P is less and vice versa.
