What type of pressure is created when air rushes into an area of lower pressure during the Venturi effect?

The correct answer relates to the nature of the Venturi effect, which occurs when a fluid (in this context, air) flows through a constricted section of pipe or chamber. As airflow passes through this constricted area, the velocity of the air increases while the pressure decreases, creating a region of lower pressure compared to the surrounding areas. This is a fundamental principle in fluid dynamics, where the pressure differential leads to the movement of air from areas of higher pressure to areas of lower pressure.

When air moves into the area of lower pressure, it is responding to the difference in pressure, which can be described as atmospheric pressure because it is the baseline pressure exerted by the weight of the atmosphere. This atmospheric pressure is what drives air into the vacuum created by the Venturi effect.

The other types of pressure mentioned do not specifically relate to this phenomenon in the same way. Static pressure pertains to the pressure exerted by a fluid at rest; differential pressure refers to the difference between two pressures at different points; and hydrostatic pressure is the pressure exerted by a fluid at rest due to the force of gravity. All these types of pressure have specific contexts that do not directly address the mechanism of air entering an area of lower pressure due to the Vent
