The steady flow of (non-viscous) liquid. Which of the two figure is incorrect?why?

Text Solution

Verified by Experts

Fig(a) is incorrect [Reason: at a construction (i.e., where the area of cross section of the tube is smaller). Flow speed is larger due to mass conservation. Consequently pressure there is smaller according to Bernoulli.s equation. We assume the fluid to be incompressible].
