Exact solutions in general relativity
In general relativity, a fluid solution is an exact solution of the Einstein field equation in which the gravitational field is produced entirely by the mass, momentum, and stress density of a fluid. In astrophysics, fluid solutions are often employed as stellar models. (It might help to think of a perfect gas as a special case of a perfect fluid.) In cosmology, fluid solutions are often used as cosmological models. (Wikipedia).
Hydraulic cylinder with fixed piston
Green cylinder with machine table reciprocates. Pressure fluid is conducted into cylinder via holes on fixed piston rod. The hoses can be stationary. In case using holes on the cylinder the hoses have to move with the cylinder. The arrows show flows of pressure fluid.

Communicating vessels is a stand alone, non enclosed system using a homogeneous fluid to help establish true level. The system will always settle and be at rest when the level in one vessel aligns with the level of the other in the system. There’s no limit to the number of vessels that can

The Incorrect Assumption Made by Fluid Dynamics, and Why It Still Works - Fluids by Parth G
Here's how scientists study how fluids flow! A fluid is any substance that deforms continually under shear stress. More simply, it is anything that can flow. Therefore, the term "fluid" usually refers to liquids and gases. Fluid dynamics is an area of physics that deals with the flow of

A way to connect fluid to a swinging cylinder. Fluid enters and leaves the swinging cylinder through its stationary pivot so flexible pipes are not needed. All pink parts are stationary. The arrows show fluid flows.
