A perfect fluid is an idealized concept in fluid dynamics and theoretical physics, particularly in the context of general relativity. Here are the key characteristics of a perfect fluid: 1. **Homogeneity**: A perfect fluid is considered to be uniform in density and pressure throughout its volume. This means that its properties do not vary from one point to another within the fluid. 2. **Isotropy**: The pressure exerted by a perfect fluid is the same in all directions.
