Isn't the pressure supposed to be internal pressure?

Yes, it's the pressure inside the fluid. At those points that pressure must match the external atmospheric pressure.bluejay27 said:Isn't the pressure supposed to be internal pressure?

Bernoulli's equation is a fundamental principle in fluid dynamics that describes the relationship between pressure, velocity, and elevation in a fluid flow. It states that the total energy of a fluid remains constant along a streamline, meaning that as the velocity of the fluid increases, the pressure decreases.

P1 = P2 is a simplified form of Bernoulli's equation that states that the pressure at two points along a streamline in a fluid flow is equal. This is significant because it allows for the calculation of fluid properties at different points in the flow using only pressure measurements.

Bernoulli's equation is used in various practical applications, such as designing aircraft wings, calculating airspeed in a wind tunnel, and understanding the flow of blood in the human circulatory system. It is also used in hydraulic systems, such as water turbines and pumps, to determine the flow rate and pressure.

Torricelli's equation is a special case of Bernoulli's equation that applies to the flow of an incompressible fluid through a small opening in a container. It states that the velocity of the fluid exiting the opening is equal to the velocity of a freely falling body under the influence of gravity at the same height.

Torricelli's equation is used in real-life scenarios, such as calculating the velocity of water flowing out of a small opening in a tank or the velocity of air exiting an air compressor. It is also useful in understanding the flow of liquids through pipes or nozzles, as well as in designing fountains and sprinkler systems.
