Study Notes
Flow Meters
- A certain type of flow meter involves the use of a characteristic dimension and the mean velocity of the flow in its Reynolds Number calculation.
Laminar Flow
- In laminar flow, the paths of all particles of the fluid are described as straight and parallel to the pipe walls.
Turbulent Flow
- Turbulent flow is characterized by swirling eddies due to transverse components of velocity.
Flow Meters (2)
