Venturi, how does fluid go from low P tube to high P tube

Click For Summary
SUMMARY

The discussion centers on the fluid dynamics principle observed in a Venturi tube, where fluid transitions from a low-pressure area to a high-pressure area downstream. This phenomenon occurs due to the acceleration of fluid as it passes through the constricted section of the Venturi, which creates a pressure differential. The fluid accelerates in the narrow section, leading to a decrease in pressure, and subsequently moves towards the wider section where pressure increases. Understanding this mechanism is crucial for applications involving fluid flow in engineering systems.

Homework Statement


How does fluid move from low pressure area in a Venturi to a high pressure area, which is downstream from the Venturi.

Homework Equations

The Attempt at a Solution


Not understanding the mechanism here, as I thought fluids only go from high pressure to low presure. Since the Venturi creates a section of low pressure, how does the fluid move to a high pressure area, which is the section of pipe where it has a larger diameter.
