I'm sure this is not a complete answer to your question, but pressure in moving fluids is governed by Bernoulli's EquationMicko said:
moo said:I think you've taken the analogy a bit too far. The pressure/volume analogy of volts/current is used mainly for a more easily understood example of something you can't see (electricity). The properties are similar, not identical.
Btw, technically the voltage won't be exactly the same at B and C, because it's farther from A to B than A to C, so there is a wee bit more voltage drop at B.

The concept of analogy between fluid mechanical and electrical system is based on the similarities between the two systems. Just like fluid flow, electrical current flows through a medium and can be manipulated by external forces. By understanding the similarities between the two systems, we can apply principles from one system to help us better understand and analyze the other.
The key elements that are common between fluid mechanical and electrical system are flow rate, pressure, resistance, and capacitance. In fluid mechanics, flow rate is the volume of fluid passing through a certain point per unit time, while in electrical systems, flow rate is the amount of charge passing through a point per unit time. Pressure is the force exerted on a certain area, which is equivalent to voltage in electrical systems. Resistance is the obstruction to flow, which is similar to resistance in electrical circuits. Finally, capacitance is the ability to store energy, which can be seen in both fluid and electrical systems.
One example of using analogy between fluid mechanical and electrical system is in the design of hydraulic systems. By using principles of electrical circuits, engineers can design efficient hydraulic systems for heavy machinery and vehicles. Another example is in the study of blood flow in the human body, where electrical analogies have been used to understand and analyze the flow of blood through the circulatory system.
While the analogy between fluid mechanical and electrical system can be useful in understanding the behavior of these systems, it is important to note that they are not identical. There are certain limitations and differences between the two systems that must be taken into account when using analogies. For example, fluid flow is affected by factors such as viscosity and turbulence, which do not have direct equivalents in electrical systems.
The concept of analogy between fluid mechanical and electrical system allows scientists and researchers to apply principles and theories from one field to another, leading to a better understanding of complex systems. It also allows for the development of new technologies and techniques by combining ideas and methods from different fields. This approach can be particularly useful in areas such as bioengineering and environmental science, where both fluid mechanics and electrical systems play a crucial role.
