Group actions (mathematics) | Dynamical systems
In mathematics, a flow formalizes the idea of the motion of particles in a fluid. Flows are ubiquitous in science, including engineering and physics. The notion of flow is basic to the study of ordinary differential equations. Informally, a flow may be viewed as a continuous motion of points over time. More formally, a flow is a group action of the real numbers on a set. The idea of a vector flow, that is, the flow determined by a vector field, occurs in the areas of differential topology, Riemannian geometry and Lie groups. Specific examples of vector flows include the geodesic flow, the Hamiltonian flow, the Ricci flow, the mean curvature flow, and Anosov flows. Flows may also be defined for systems of random variables and stochastic processes, and occur in the study of ergodic dynamical systems. The most celebrated of these is perhaps the Bernoulli flow. (Wikipedia).

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

Volume Flow Rate & Mass Flow Rate - Fluid Dynamics Physics Problems
This physics video tutorial provides a basic introduction into mass flow rate and volume flow rate. The mass flow rate is the change in mass per unit time. It is also equal to the product of the fluid density, cross sectional area and the speed of the fluid in a pipe. The volume flow ra
