1. Uniform flow: Uniform flow is a type of flow in which the velocity of the fluid at any given point remains constant over time. This means that the flow is the same at all points along the flow path.

2. Steady flow: Steady flow is a type of flow in which the velocity of the fluid at any given point does not change with time. This means that the flow rate remains constant over time.

3. Unsteady flow: Unsteady flow is a type of flow in which the velocity of the fluid at any given point changes with time. This can be due to changes in flow rate, pressure, or other factors.

4. Mean velocity: Mean velocity is the average velocity of a fluid flow over a certain period of time. It is calculated by dividing the total flow rate by the cross-sectional area of the flow. Mean velocity is often used in fluid dynamics to analyze and describe the overall behavior of a flow.
