    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)

    • One type of flow meter does not obstruct the flow path of the fluid.

    Reynolds Number

    • The formula for Reynolds Number ($R_e$) used to classify fluid flows is not provided in the text.
